zz, no, i don't want "proof". i'd like to know about your experiences and thoughts.
i also do not think people act totally independent of each other.
i think people (and places, other creatures and plants, anything you come in contact with) influence each other in many ways.
i want to know how you sense something called "culture", where it locates, how you know if it has changed, etc.
i hope that clarifies, at least a little.... :)
edited to add:
so, taking "rape culture" as an example, what would cause you to say that it does or does not exist? or any other aspect of what you consider "culture" (if you'd rather use another)?
it may seem strange to you, but i don't use the word (culture)....like a lot of other words i don't use which appear obvious and common to most people i talk with....i've intentionally removed many words from my speech and writing, mostly nouns used as concepts and/or broad representations for what i observe as dynamic, moving, transitory, varying, and fluctuating (by person(s), by place, by instance, by degree) phenomena, feelings, behaviors, thought patterns....
