They don't.

I consider the moral-fascism of modern illiberal progressive rhetoric to be rather abhorrent. Are you fine with being socially outcast?
This is counterfactual, and I'm not interested in debating facts.

I'm sorry, but this is word salad. You don't know any of my concrete political positions.

I am extremely comfortable with reactionaries being socially outcast. I belong to a few different groups that are traditionally (and violently) targeted when reactionary movements gain social and political power. Minimizing the ability of reactionaries to undermine systems of government and public discourse directly serves my end of continuing to exist in a liberal democracy. I'd quote Popper, but that's a little bit too cliche at this point.
I am, however, willing to support a movement that results in conservative content being demonetized if American conservatism continues to pander to and fall back on its racist and reactionary cores. It isn't clear to me why social disapprobation and pressure on the whole to excise reactionaries is inappropriate in this context.
