For real. While sociology might be a safe spot to come out, sometimes it doesn't seem like a safe spot to joke around sometimes. The extreme liberal ideology makes it hard to make joke (although at times they will be tasteless), because all of the ''bleeding hearts" take everything you say so seriously. I didn't view the original comment as overly offensive, in fact--i thought it was a joke. Judging by the last reply, I guess it wasn't. However, I really feel like in sociology you're allowed to speak your mind, so long as your mind aligns with a liberal ideology. Makes it hard for people who like "shock value" comedy.
To the OP--i can almost promise you that it will not be a problem to come out to your new department, and good luck.
