Misogynist, slut-shaming ableist cis-scum blaming a womyn for his problems. Check your privilege.
Regardless of what position the authors of the posts in this thread take, I've yet to encounter a single one accuse DU or Codex staff of being transphobic (though truth be told, I have not read every single post in the thread).
What I have seen though are plenty of disturbing, clearly homophobic, misogynistic, or transphobic remarks throughout this thread and others, from posts whose authors may or may not consciously understand that such statements are homophobic, misogynistic, or transphobic.
Such discriminatory mindsets have as much to do with culture (certainly a force not lacking in the Brofistgate) as with ignorance. For example, I read in one of these threads where the author, whom I cannot remember, states that the fists are inflated, and that the women get more fisting than the men, where he only considers "genetic" females as females (that is, no Y chromosome, period), and continues on on how someone born "male" will receive fewer fists unless he also identifies as a "female", which is unnatural. This completely undermines the female and the transsexual individuals and is a bigoted mindset, even if no ill-intent is on purpose. It's the same kind of reasoning that people used to think that jewish people, people of african-american descent and also womyn should not naturally be a part of the forum population.
Fisting isn't as black-or-white (or more apt, male-or-female) as people think. The whole notion of fists, in fact, is pretty archaic. All I have to do to is remind of the futuresque system occasionally practiced by this forum, with parrots, rainbows and other pretty pictures.
