I was called a TERF at work the other day. Someone made a comment about JKR and I just said "JKR said nothing wrong". There was an audible gasp from the others around but the conversation stopped immediately when someone else walked in and asked what was going on. The person who made the comment about JKR in the first place said "we have some trans exclusionary radical feminism going on over here" and pointed at me. I just said "I'm not a trans exclusionary radical feminist". I honestly didn't expect it and didn't have an response prepared.
DP has said I shouldn't make comments like that again as he's worried about me losing my job, so it probably won't happen again, but what should I have said back? What's the correct response to it?
