At the very least we need to consider the culture. In our culture there are things where we consider them unambigously immoral and anyone engaging in them or even defending them is as well. But we have other things that are at least controversial to most people (e.g. eating animals). In the latter case, I find it perfectly fine to argue against it, even passionately so. But it's absolutely not ok to demonize or ostracise people for it. I feel like, as a society, we knew this until recently. At least most of us did.
