pretty much anyone who has had much to do with type*
Simply because of how abused the font is, aside from it being a terrible font in general. The font was originally designed for use with designs related to comics (who knew?) or children; not for the extreme overuse that we now see almost every day. Comic Sans is constantly used inappropriately, for things like; a player name on the back of a basketball shirt, a grave marker, teacher reviews for a graphic design department etc.
People who do not hate it for it's overuse, hate it for it's poor aesthetics. The kerning and weighting of the font are inconsistent or unbalanced, and the font isn't really suitable for use in a comic at all.
Q: My previous one. I wanna see if anyone can answer it.
