Asking someone if they are a bot is a legitimate question if there was no conversation before that and if they are acting funny. - You would be surprised but there are actual bots doing dungeons.

I don't see the problem asking about this, even tho it would be better to just ask any other question to get some response out of the character.

The question may seem a little bit insensitive, but the most offensive part of the conversation was trying to ignore the problem. This black mage could have learned something and avoid the problems in their future. But instead the tank stepped in, who by the way seems like having a "love interest" in the blm, and just blowed the whole thing out of proportions.

This is one of the issues with this community. We try to be sensitive so much that we actually become extremely aggresive and toxic towards any form of critique.
