I think it means "just asking questions"? So to bring it back to the topic of the thread, if someone wants to question anyone in here who carries the torch for some social justice cause, or challenge any of the studies presented, they are immediately accused of JAQing off, racism, being conservative (same thing) etc. etc. This is demonstrated in this very thread.
I'm personally convinced there is some degree of racism in the job market, which along with many other historical reasons justifies affirmative action programs. I hope they are not necessary for ever. That does not mean I think all of these issues shouldn't be subject to strong criticism both within academia and the public sphere, something that appears to many people is simply stupid and racist. Judging by the constant
reports of intimidation on campus of anyone who doesn't tow the line, I think it's fair to be concerned academia is going through some version of what happens on these forums.
