This approach works for a lot of different topics.

For example, I’m an atheist. If someone I’m talking to is just brings up their faith I’m not going to go out of my way to start an arguement.

But if they’re start being argumentative, like coming up with bad faith arguments to bash gays or atheists, then I’ll push back. Usually gently at first, but if they keep going then the kiddie gloves come off.

Thankfully, most people I interact with (at least irl) know to not be an asshole. I get that not everybody has that luxury though.
