I'm cis-male, maybe I'm not completely typical, but I'm certainly someone who has the benefit of male privilege in this society.
I've not noticed too much sexism directed at cis-males. Of course I don't read everything here, so I'm probably missing things, but the general attitudes here I've felt towards me was not particularly sexist.
Yes, some people make universal statements about groups of people - and cis-men are one group stereotyped here. But I've also seen MTFs and FTMs stereotyped, intersexed people stereotyped, spouses stereotyped, etc, here. And I probably see way more *here* directed at subgroups of the gender community than towards cis-men. So with that in mind, the occasional stereotype about cis-males doesn't particularly bother me (although I may speak up!). The idea of stereotypes on the other hand *does* bother me, whether directed at me or someone else.
