i guess every one here is a human. i am a human. Unless you call for the extermination of humanity or a continous ideology of self hate for humans, it might be better to foster the best in humanity and fight the worst of it. Just as there is a fascist environmentalism (
http://en.wikipedia.org/wiki/Ecofascism ), humanist ideas and positions could have been used to justify some bad things.
reason 5 sounds like a humanist has to believe in some kind of religious myth of progress. Progress can refer to overall improvement in humanity´s condition just as in can mean a small good change on a specific issue. For example it is clear in the US there has been some progress in the situation of african americans as far as breaking racist barriers and apartheid laws. the opposite of progress will be regression and so that also happens and humanists will also think that is possible and as such progress could not be seen as something that will happen no matter what.
I don´t see science as good on itself and science is mediated by corporate interests just like almost anything today. From the human posibility of empathy (which is not as clear in non-human animals) one can arrive at a position of concern for exploitation of species and environments.
So "humanism" created technocrats, scientists, bureaucrats, etc. Maybe in part although you might have to be more specific and instead of saying something so broad such as "humanists" you might have to blame monarchies, the rising bourgoise, etc. As far as science i don´t think scientists and science are "bad" per se. From the individualism of humanism one can decide to affirm one´s subjectivity and resist and reject bureaucratism. A humanist will defend the instrinsic value in individuals and so obviously from such a position one can oppose the instrumentalization of humans. Also some humanism tends more to aesthetics and art rather than with science.
On point 7 i think you can accuse many things of that and not just humanism. It will depend if a particular humanist is racist in order that that person will try to accomodate racism in humanism. Otherwise humanism will emphasize the human species as being one and so racism will be considered absurd. In fact scientific racism (
http://en.wikipedia.org/wiki/Scientific_racism) tried to prove that non-white people were not humans or were a "sub-especies" of humans. The major french humanist philosopher Michel de Montaigne opposed the colonization of the Americas and in an essay called "Of Canniblas" he strongly came up againts caricaturizations of american people as "savages". As such "I find that there is nothing barbarous and savage in this nation, by anything that I can gather, excepting, that every one gives the title of barbarism to everything that is not in use in his own country. As, indeed, we have no other level of truth and reason, than the example and idea of the opinions and customs of the place wherein we live: there is always the perfect religion, there the perfect government, there the most exact and accomplished usage of all things. They are savages at the same rate that we say fruit are wild, which nature produces of herself and by her own ordinary progress; whereas in truth, we ought rather to call those wild, whose natures we have changed by our artifice, and diverted from the common order...But there never was any opinion so irregular, as to excuse treachery, disloyalty, tyranny, and cruelty, which are our familiar vices. We may then call these people barbarous, in respect to the rules of reason: but not in respect to ourselves, who in all sorts of barbarity exceed them."

They were largely absorbed in recovering (and competing with) their own classical past and engaging in violent theological and political disputes among themselves. Yet some Europeans were profoundly shaken by the new discoveries into realizing that much of the world thought and lived very differently from what was then known as "Christendom." No writer was more strongly moved to view his own society from a new perspective in the light of reports brought back of the habits of the natives of the "New World" than Michel de Montaigne. He began a long tradition of using non-European peoples as a basis for engaging in a critique of his own culture, undoubtedly in the process romanticizing what Jean-Jacques Rousseau would later call "the noble savage." It is a theme which still appeals to many Westerners."

As far as the citation by Stirner i will say that any concept can be instrumentalized, not just that of humanity and humanism. Even the concept of "individual" is instrumentalized today by right wing laisses faire capitalists in order that people become acritical consumerists saying that there they are being free because they choose what to buy, and also believers that private property is the main base of freedom without any distinction between corporate and capitalist property and things one uses (personal property) such as a toothbrush or a book.
Anyway it seems to me some people here might need to check two articles before talking seriously about humanism:
http://en.wikipedia.org/wiki/Secular_humanism
http://en.wikipedia.org/wiki/Renaissance_humanism
i find the following interesting "Postmodern critics who are self-described anti-humanists, such as Jean-François Lyotard and Michel Foucault, have asserted that humanism posits an overarching and excessively abstract notion of humanity or universal human nature, which can then be used as a pretext for imperialism and domination of those deemed somehow less than human. Philosopher Kate Soper[61] notes that by faulting humanism for falling short of its own benevolent ideals, anti-humanism thus frequently "secretes a humanist rhetoric".[62]" In his book, Humanism (1997), Tony Davies calls these critics "humanist anti-humanists" "
