Not sure about you, but recently, a lot more of those online behaviors have started appearing IRL.

That means that people already did these things, but, like alcohol, the Internet lowers the inhibitions to not behave like that. It's a pretty short leap to say that, if you spend a lot of time online, these behaviors will become a large part of who you are on and off the Internet.

Does it mean that people can't relearn how not to act like that? No, but it's gonna be hard.
