You’re assuming that an antisemite would be thinking rationally. jew-hatred doesn’t tend to be based in rational thinking. Rather it is a basic expression of spite and vitriol. Being “pro-palestine” at the same time gives a convenient excuse to act out and a mass of people to hide amongst, emboldening the ones who otherwise wouldn’t dare.
In any case, I hope that’s enough to answer your original question.
Do not kill, or through intentional action cause physical harm to another human being, except in defence.
Every human has the right to their own body, thoughts and words, upon which nothing except the above law shall infringe.
Where it does not conflict with previous laws, respect physical property of the public and other individuals - it is not to be destroyed, taken or abused without permission of its holder(s).
