post #987294 would fall under all of these tags. post #521930 has mindreading. post #836415 has an insult. I understand that these posts have different meanings given a more thorough context, but based on danbooru's rule of tagging what you see, these tags would obviously apply.
The use of pov_X tags is sort of messed up right now. According to forum #60887 I don't think there was a conscensus last time.
insult and mindreading seem fine to me (I'm surprised we don't seem to have the mindreading one already actually). I think "insult" sounds too narrow for the concept but I don't really know what you could use instead.
