I think you're pulling a lot of that shit out of your ass almost everyone likes Tony and /co/ is full of different people who voiced their opinion or just do it for trolling so don't take ot personal. Two days ago we had a thread where the OP shat on Cap and we have multiple threads were people shit on Carol. Tony hate is not unique here, not to mention the Tonyautist and the way this thread was started it was pretty wanky, of course you will have people reacting negatively to it.
As for normies, I really see more Tonyfags spewing hate for other characters than I see actual Tony hate. Tumblr and fujoshits especially can be pretty autistic about Tony being protected and loved while also wanking on Tonysuffering. The Ao3 tony hate tags are also pretty empty meanwhile the anti TeamCap or anti Steve tags are full of fics with character assasination and characters shitting on them to prop Tony up. Hell I've seen people who convinced themselves Bucky would end up hating Steve in favor of Tony.>>102863139
