If you think "debate" threads that start with a transphobic premise or encourage posts that attack the legitimacy of trans people that always result in a quagmire of chromosomes/disclosure/penis posts are the right venue for education, you are going to burn out very quickly.
I do not think the question "would you date someone who is transgender" is either off limits or transphobic.
The thread was started asking if, in the two years since the original thread, opinions had changed at all on NeoGAF. That's a totally valid question to ask, and people should have the right to say no. I take issue with those who give their answers in overly negative or insulting ways, but that doesn't mean the entire conversation is offensive.
Like it or not, people should have the right to not agree with us, believe us, want to date us, or even like us, so long as those things don't turn into actual action taken against us. The only way to change a lot of minds like that is to allow conversations to happen, and try to explain the other sidenot to tell them that they can't have said conversations. (Again, so long as they're actual conversations, not one-sided attacks on a segment of people. I never felt like that thread was such a thing.)
And I've been jumping into those kinds of conversations on here for years, since before this thread was started. I'm not worried about getting burned out. *heh*
