Because the safety of society at large, especially if we look at the perception of it rather than the real goals, can translate directly into oppression of those who are perceived to be a threat. The whole "build the wall" thing is pitched as being about safety of society, for example. There are people in this country - including prominent elected politicians representing party that dominates state legislatures, and that has broad popular support in most those states - who sincerely believe that BLM and CAIR are terrorist organizations. There's that whole "BDS is anti-Semitism" thing, and some countries already have laws on the books that make it a felony to participate.

Would you say that the political and judicial system of our societies is fair, or is it biased against minorities? If it's biased, why do you expect it to enforce any such "safety of society" laws in a way that is not similarly biased towards the groups that already are the beneficiaries of that society?
