Respond super excited, like when you meet someone who shares the same niche hobby than you: "I like girls too! So tell me, what have you found to be the best technic to eat pussy?"
What prompted that disclosure? Could she smell the horniness emanating from Anon? Did he, as he noticed she was a woman, give off a vibe like a starving cartoon wolf imagining the main character as comprised entirely of sausages?
In this case its a bit different but what i see is that everything is oversexualized but the effect of that is people are actually more lonely because every social interaction you have with anyone who could be a sexual partner automatically becomes strange.
Sorry that you feel obligated to mention this based on your past experiences. I hope our interactions are professional. Please let me know if I step over a line... my jokes are sometimes a little off but never misogynistic maybe a little dark, but I work on it.
With that out of the way ... my Name is Anon, I am happily married. Now.. let's Beginn =]
Is that polite though? I get that it isn't explicitly rude but I pretty much only use that phrase as short hand for "why are you talking about this you fucking weirdo?" I think it's subtly rude at best.
Most politeness is about rephrasing rudeness in a subtle way. What OP's fictional coworker did in this fictional story is explicitly rude as it assumes the worst from meeting a new person, the most appropriate response would be something that is subtly, but noticeably, rude.
If a team lead, sight unseen, just tells you their sexual preference without any context or follow-up then yeah that's fucking weird and they're a weirdo.
