I think it's extremely important to separate opinions on Israel, a sovereign state where both Jewish people and Arabs and other ethnicities live and are welcome, from opinions on Jewish people. Many Jewish people around the world and inside Israel in fact are strongly against Israel's actions. Some even participate in BDS or other protest movements, even calling for sanctions of Israel. Similarly, many people oppose the USA's actions. Some Texans even want to secede, affecting the borders of the USA. That doesn't make them antisemitic (even though the majority of the world's Jewish population outside Israel lives in the USA), nor anti-caucasian, nor anti-black, nor anti-hispanic (though of course some of them could also be some of these things). There really is no rational reason to say that opposing Israel's actions or wanting it to accommodate certain borders for the Palestinian territories is antisemitic. It is anti-Israel and that's it.
