Have you heard of Daryl Davis? Black dude who convicted KKK members to quit just by being friends with them. I think empathy might be the key, I.e. its hard to be homophobic if your friend is gay.

That’s the energy I like to approach discourse with. Its harder online but it is possible.

Genuine question, why do you need to change peoples beliefs? Idk I find that 95% of people are pleasant to talk to and share your views with if you just speak with them nicely and try to understand their POV. And that applies to people who I vehemently disagree with.
