The truth is that what is right is decided by how well the arguments for it can convince people.
If you look back far enough, the arguments were: my army is stronger than you. As you get closer to the present, we tend to like using better arguments (the veil of ignorance for example https://en.wikipedia.org/wiki/Veil_of_ignorance).
It's based on notions like the veil of ignorance that we can say maybe every human should have property rights lest the group we're part of today lose it when the balance of power shifts.
That's why I believe that jews should have property rights, but don't believe that advocating against what I believe should be stifled. I am confident enough that my argument is better than theirs to not need to prevent their speech if you prefer. I also don't believe that we should stifle: climate change denial, flat earthers, religious people, pro-life people and a host of other people that I believe are wrong.
