Normal masculinity is simply existing and not giving a fuck how other people expect you to live. There's almost no point in discussing it more as the left is already very comfortable with discussing the idea that you are who you are and you can be proud of that. That message is literally everywhere.
Toxic masculinity has to be discussed because people are being made to confuse being toxic with being "strong" which is something the right is creating. Their image of a "real man" is toxic.
It's like the whole "racist right winger" or "neonazi" labels given to a politician, but then some random right winger gets all bent out of shape as if they were called a Nazi... They weren't even part of the conversation, they decided to take on that guilt. It's the same with toxic masculinity. If you're not expressing the things that are discussed within that subject then they aren't talking about you, you're more than likely "performing" normal masculinity. It's not the fault of the people having the conversation that someone else chose to feel offended by it when it wasn't about them at all.
