So what you’re saying is that you personally can’t be convinced by a post, and you’re extending that out to everyone else.
This seems like a form of solipsism. If you don’t believe the posts you’re surrounded by are authentic, then nothing anyone says can convince you otherwise.
Like for instance, I could tell you I’ve been convinced by things people have said online. Sometimes it’s in a context of debate, sometimes not. But if you think I’m only cynically saying that for the points, then I’m obviously just lying. It’s a perfect circle of protection.
Ultimately only you can decide if you’re open to being convinced. The problem comes when you decide that’s everyone else’s problem. I can’t say what’s in your head and it’s hard to figure out what you mean here.
I’d be interested to know what your online media diet is, because honestly I think most debate bros out there aren’t doing much of any worth, except again maybe performing to an audience. I don’t know what to say here. You say your head’s a mess, and I tend to agree. I can’t make head nor tails of what you’re saying. It sounds like you’re monologuing to yourself, and I’m not really qualified to interpret it. Only you are.
