Yeah some people did cheer 9/11 but these are morally weak people.
If Israel killed 2 million gazans tomorrow they could say look at what they did and I don’t think the people who said the 9/11 terrorists had their reason would endorse killing 2 million Muslims.
This is what moral reasoning is, just because 1 side isn’t perfect doesn’t mean that the other side is evil or wrong.
You can see that the Islamic fascists rely obscuring issues, propaganda, yelling slogans in unison.
To parse facts is difficult but it is not difficult to see that islam is a fascist ideaology unwilling to be peaceful and Israel has made numerous steps and concessions to peace.
You could say that ISIS is justified to genocide the kurds for some reason, you can say the Nazis were justified, that Germany was decimated… It doesn’t occur in a vacuum, but then to turn around and be sympathetic to the Nazis who were bombed? Yeah many people are, they see the Nazis as justified and lament their oppression, but they are idiots.
