From one Non-Jewish person to another,
If your activism for Palestine claims that Jewish people control the media, you're antisemitic.
If your activism for Palestine claims that Jewish people deserve to be killed, mass-evicted or sorted into "good" and "bad" Jewish people, you're antisemitic.
If your activism for Palestine claims that all Jewish people are Zionists, you're generalising and antisemitic.
If your activism for Palestine is antisemitic, you are actively harming Jewish and Palestinian populations worldwide with your rhetoric. You don't really support Palestine, you just hate Jewish people - and if that is what your activism is, it's not true activism and we don't need you in this movement.
If you're not a safe space for all, I'm not the blog to follow.
