Did you admit that that you were repeating other’s arguments, or did you pretend they were your own?
There are, roughly speaking, two kinds of internet debaters:
One kind argues and debates becasue they enjoy the intellectual process. They understand that losing a debate is a good thing, as it makes you go and look facts up, find better arguments, or maybe even consider the possibility that the other guy has a good point.
The other kind enjoys the visceral thrill of attacking someone, and the security blanket of repeating their own unquestioned beliefs. They think the purpose of a debate is to win.
You’re in the second group, and it’s not a group any adult should be proud to be in.
