and you're suggesting we shut up and keep quiet when we KNOW we are RIGHT? That is not going to happen. Submitting to tantrums only makes those people get stronger.
Don't get me wrong, it's not about being quiet either, but I think there are better ways of exposing your point of view¹. Before I became more left-aligned, I had to read several articles and listen a lot, but the tone wasn't abrasive as in most discussions. (Sometimes it was and it made me get defensive, but I knew from past experience that maybe I was wrong again, then I had to listen to see their point. After a few days, it clicked and I started understanding it better).
Of course, if someone doesn't want to be helped, it's not you who is going to change it. But, I think the 'adversary' is always more compelling to learn if you express it in a sincere way, more neutral/polite instead of attacking. And you will learn too.
¹Just to be clear, I'm talking about discussions on the Internet or in person.
