I hope my colleagues don't ask my opinion on therians

It scares me the fact therianthropy is coming out of the bubble even outside the US.

This subject is living rent free in my head all the afternoon, and all beacause a professor told during the class that some days ago he was watching a lecture and in some moment the speaker talked about therians; everything he interpreted of therians is the typical answer you'll expect of someone when therianthropy is treated as a serious question, so it doesn't worth transcribe it here. Many of my colleagues agreed with him, and one of my friends also laughed at that.
I did feel annoyed (as a therian myself), but I tried to hide my feelings towards this while me and my friends were playing truco. I guess I did the right thing since advocating for us could bring me a strange reputation or they could ask me something that would force me to come out.

Am I right for being worried or am I just being overly sensitive about a topic that may never be discussed among them again?
