@coffee addict I don’t follow your logic. They support Ukraine (and often Taiwan) because they believe in sovereignty and self-determination for indigenous peoples. The same would apply to the Palestinians.
Your logic is an effective argument only if the liberal stance on Ukraine and Taiwan was somehow caused by the fact that Russia and China have the opposite stance. This isn’t the case (liberal opinion is not “the opposite of Russia and China). Therefore, the fact that Russia and China don’t have a strong pro-Israel stance is irrelevant.
I think your post is proof that often, some college may be helpful.
