I think you just shouldn't have done it at all. I get you're proud about whatever you believe in, watch or whatever.
But this IS inappropriate. It's not just a person being happy, it's literal pornography. If I showed you a picture of a murderer standing behind some dead bodies with a smile on his face saying "this is just who I am! I'm just being happy!", would you accept it?
All I'm saying is, it's an irrelevant temp that you know would stir up controversy in the stream where everything is controversial. Posting this is anywhere else wouldn't get as much hate, why post it here?
I also honestly couldn't care less about your position in office. If I was gonna get you out of office, I'd do it near the start of the term, not near the end. But you're in office and I accept it so, you do you. Just don't make the stream more complicated as it already is.
