Alas, there is no algorithm yet for "truth".
I've thought for a long time that when the generation that fought in the war, or even grew up in it, has died out, that's when idiots like this student will be free to make something terrible rise. Fight for freedoms like speech while you can.
If you think WWII wasn't special in significance then I can only say you're entitled to your opinion.
Log out of Twitter, that's my advice.
However, I don't know many places where mainstream politics would accept political violence as anything but extreme in almost every case. I'm not sure the fringe is growing, but to come round to my initial point, I'm worried that it will after the last WWII generation dies out.
I know that the US has a reputation for producing idiots but believe me, they exist in other places too, hence why I didn't specify the States, but you feel free to make it all about you.
