I feel sorry for you if you seriously belive that antifa is in any way a terrorist organization.
Even when you say it's easy to research and find those facts, you just prove that you did not look at these sources with a critical eye.
If the current US government, either Trump in the lead says something, it doesn't make it a fact. We know, for a fact, with countless piles of evidence that they lie again and again.
They defend Nazis and attack anti-fascists. Think about it.
