There was a time when the Nazis thought they were right, and those fighting against them were the enemy.
That's very true. The Nazis and a good number of the people of Germany were trying to achieve the very best outcome for the aryan race in the aftermath of WW1. They started out just trying to build up their nation after the injustice they felt they'd suffered, and in the end they didn't care whose expense it came at for them to put right those injustices. They didn't care if it made them anti-semitic. They were standing up for the German people, getting the best they could for them.
You can stand up for the rights of one group of people all you like, but if you start to not care whose expense it comes at you have a problem. I say the same to extreme TRAs as I do to extreme feminists. If your cause causes you not to care who else gets hurt you've gone too far.
I really didn't mean to upset you, I really didn't, that's not something I want. I'm just saying my piece on the subject.
