Dot didn't write: "[Anarchism is] intellectually lazy itself."
Absolutely. As unfortunate as it is to admit, there is a strong current of populist anti-intellectualism within the anarchist milieu itself. The irony is that this same tendency can be seen within Donald Trump's core base of supporters, who have stylized themselves as these "John Q. Everyman, Working Class Hero" types who are taking on the globalist corporate fat cats who want to ship their jobs overseas. While I would agree that institutionalized academia definitely needs to be critiqued, critiquing it on the grounds that it's "too intellectual" is just code for saying "I'm too stupid to understand what those ivory academics are talking about." It's certainly a valid critique to say that academia as a bureaucratic institution reflects the capitalist mental/manual division of labour and, as such, reduces "the Intellectual" to a 'specialist' or 'expert' in intellectual activity. It also isn't entirely inaccurate to say that universities have, to a significant extent, become havens for self-righteous left-activist PC police who want to cram their sensibilities down everyone else's throats.
However, it is nothing less than a celebration of idiocy to conclude from all this that anarchists need to be "less intellectual." If anything, it's an argument for highjacking the intellectual tools that universities make available and using them for our own purposes. It would also be a mistake to say that this anti-intellectual streak is the sole province of the 'leftist' contingent of the anarchist milieu because I've seen it expressed among certain segments of the 'anti-civ' tendency as well. Without mentioning any names, it is particularly common among those who refuse to even engage with certain concepts and theorists because they're deemed to be too 'Postmodern,' too 'elitist,' too 'esoteric,' etc. This attitude is particularly common among those for whom anthropology is considered to be the Holy Grail of the social sciences. ;) So, no, I don't buy the idea that anarchists are "too intellectual." If anything, they aren't intellectual enough and need to seriously ratchet up their intellectual game.
