Hmm well if you don’t mind a bit of unsolicited advice, I would say that (from the frustrations you express) maybe you, like most of us, enter discussions online with a mind to convince others of the absolute truth of what you believe in. It is actually more productive to listen to them, then ask why they feel the way they do about certain topics, and then try to see if you can find common ground with them. Only then can you perhaps influence their views a little. But if you are earnest about the exchange, you must allow them to influence you too.

I know that’s hard, I fail often myself and become frustrated.

Of course there are conspiracy theories and falsehoods that are absolutely bonkers and it stymies me too why some people will gobble it all up, but a wise person is never too sure of their own truths either. Funny thing is we are all biased one way or another, we just tend to be blind to our own biases. Of course some truths are supported by more evidence than others, but especially when it comes to politics it is less about the absolute truth of a matter than it is about adopting a particular perspective. No single perspective is more valid than others inherently. It is all just ways of looking at things. Of course one can try and come up with objective criteria, but that too is quite hard.
