In particular, the whole LGBT and feminist and so on community seems to be prone to taking unnecessary offense

But to be serious I extended a fair amount of effort trying to get value and some understating from the feminist blogosphere and some academic papers, but I've been mostly bitterly disappointed with the horrible epistemology

I'd like to think that were I gay, being grouped with the feminist rather than transgendered people would be the offensive thing, if any. Not just for its epistemology, but because it is a set of beliefs and ways of acquiring beliefs rather than an orientation, regardless of its epistemology.
