You're still not getting it.

You're talking about measured health impacts on an overall population not about ideologies. The idea that other ideologies are anti-social or harmful precludes the idea that your view of society is the correct one. That works out fine so long as you maintain the majority, but if the tides of time change against you then the very opposite would be true.

A rural community of racist white people in the US aren't anti-social or harmed by their view until that dynamic changes, such as a person of color entering the community. Objectively that community lacks diversity of experience which promotes growth and development in the community (this is referencing your discussion about objective measures), but the desire to not change is part of why we these people are called conservatives and isn't fundamentally wrong. The thing you are repeatedly missing is that calling these ideologies anti-social or undesirable and not deserving of protection under the law only is your express opinion, not an objective truth, and you only support this opinion so long as you remain part of the in crowd. If the situation were reversed your opinion on whether all ideologies deserve the protection of law would reverse as well.

You’re operating under some sort of legislation=ethics and morals framework that’s flawed in incredibly fundamental ways. Any ideology that violates the social contract cannot be protected by it.

It's quite the opposite, I'm declaring that legislation is not equal to ethics. Ethics function purely on an implied social contract whereas laws function on explicit statements. Laws allow people of opposing opinions to coexist and instead of relying on implied incompatible social contracts they all have equal protection under the law. This by nature is the difference between Just and Fair or Equality and Equitable.
