Explaining what this person does takes more than two sentences, pardon my "obsession". That was unnecessarily rude of you - this user is not avoidable for me due to them consistently posting these exact kinds of questions on several boards that I happen to frequent for lore reading. I don't have to chase them, and the end of this post'll mention why I don't just ignore them.
A discussion is not asking if Warcraft's Kul Tiran shoeshiners would be disgusted by having to shine the shoes of an Elf, or if all Elves truly do think that Trolls are "axe-throwing primitives", to quote the exact wording they use literally every time they referred to Trolls in that post. A discussion is not asking if Princess Talanji would have to kiss the floor in front of Sylvanas' feet, or if she would hate working for her despite having to, given that the characters have their interactions play out onscreen for the player in a very amicable manner. It is fishing for hearing certain things.
That they are free to like what they like, as everyone is, but users are incessantly pestered by this individual to cater to his fetish concerning domination and racial superiority/rank-and-file superiority complexes. It interferes with what could have been interesting discussions on boards I enjoy reading, and I'm very uncomfortable with well-meaning users being used and led into fake discussions for the sake of this user getting their rocks off.
I know full well how to deal with the toxicity of others, and don't consider this person toxic. They aren't rude, they don't start angry, insulting arguments, but I doubt anyone would be happy to learn that the nice discussion they were invested in having was just a front for someone to hear 'yes, they would be executed if they refused their orders and would hate working for that woman in power'.
If you want to just ignore what I typed and label me as obsessive for typing more than two sentences and not being aloof, then fine, but I'm just not comfortable with this behavior happening on so many subreddits.
