I agree, but not regarding anti Semitism.
That was already a problem before twitter, anti Semitism comes from people noticing that western governments are controlled by zionists.
People get actual Jews confused with Zionists because Zionists are pretending to be Jews.
Same way that ISIS are pretending to be Muslims.
You can't blame twitter for that.
But twitter is a cesspit of garbage, he's right about that part.
