But the point I'm making is that being against interracial marriage, even if it were somehow just about something like marriage is definitionally not interracial would rightly be considered cancelable to most people. The reason I think that the examples seem different is merely that their badness seems different to you. There isn't some set of things that are clearly ok to sanction someone over and some set that aren't. It's all merely about how clearcut you think the issue is and that will always be political. To be clear though I do think this is a clear cut issue. Not to get into the weeds on it, but I do think your options are either believing that marriage should not be a function of government at all, or believing that marriage between two same sex people should be allowed
