Ye saying he's "going to go defcon 3 on the Jews" is absolutely antisemitic and absolutely why he got restricted on Twitter. [0] That's the tweet that was received moderation, and its subject matter is very clear. I don't see how one could be unclear of why that got removed or unclear that's it's antisemitic.
Wearing a shirt doesn't magical erase one's behavior. "White lives matter," "All lives matter", it does not matter; what a shirt says won't make his antisemitic comments not antisemitic. Kinda like staring a sentence "I'm not a racist but..." doesn't make whatever racist comment that follows not racist.
As an aside him wearing the shirt isn't in support of Jews or white lives, it's him being funny/ironic. Read your own source. When you have a "<minority> lives matter" it's about speaking up for an un/under-represented group. White lives matter is a joke, as they are the majority. To paraphrase your source, it's funny because it's a black man stating the obvious.
