You asked for evidence, not an undeniable proof. If you can't understand how it's suspicious that Palestinians are present on Japanese social media of all places then you're not worth the conversation. I don't have the interest to play researcher just for your sake and even if I did, let's be honest, you wouldn't hear it. Similarly, I could say I wish Hitler finished the job and you'd still call me a Zionist so really there's no point to this exchange.
