I'm not sure if this is unpopular per se, but yeah, I don't think people on here are voting in a consistent way and that makes it confusing to know which posts are actually unpopular opinions.
I have seen people say something like "nice unpopular opinion, take my upvote", but the votes don't reflect that sentiment when a truly unpopular opinion is posted and it's heavily downvoted. Also, in reverse, posts that appear to be agreed-upon popular opinions are massively upvoted.
I think a good number of people on here downvote opinions they don't agree with, which is a reflex I can empathize with, but doing that might discourage people to post here. So, I think people should upvoting posts you don't agree with.
And I think that it should be posted clearly for people to read and refer to in the about section of the community. I think maybe it should be a pinned post too (at least for a little while) because I don't think everyone reads the about sections.
TL;DR — For the sake of clarity, there should be a posted rule that basically states: upvotes mean you don't agree with the opinion and downvotes mean you agree. So, if you agree with this post please downvote it.
No, not at the time it was made, but the modern LGBTQIA+ lexicon has moved on from it
Fun fact: On Drag Race, Ru used to give messages to the contestants and called it "She-mail", but they (reluctantly) stopped calling it that due to heavy viewer criticism
Edit: I should have also said the "She-mail" thing was heavily criticized by former contestants as well, which was probably an additional factor that made the show change the name
