i don't recognise the feminist section as the nest of vicious bullying that it is being portrayed as here - this hasn't been my experience, nor have i seen it
admittedly i am not on every thread, though i do lurk
i have seen, posters disagree, quite strongly, and then go on to discuss other things on other threads quite amicably - i am thinking particularly certain pro and anti porn/sex industry posters
myself, i can think of posters that i have disagreed with re: trans, gender and feminism, but done so respectfully
i suppose the difference is that everyone involved had accepted as a basic premise that women were human, with all the rights that this entails
it is very hard (impossible) to discuss with someone who, for instance, thinks that sometimes women deserve x, or it is their own fault if y, or who insists that the fact that z happens to some alarming proportion of women is purely coincidental and is most aggrieved at any sugeestion that it might indicate some kind of pattern worthy of being looked at
