I'm stupid and an idiot
That is doubtful. I think you overthink too much. Real stupid people and idiots do usually not realize their condition. which makes them so obnoxious.
so I never know when something I think is right is actually wrong
Read about formal arguments. For some stuff you can deduce what is right by following logic. And if you find that what you thought was true derived by faulty logic or faulty premises you will have answers too. But for some stuff it cannot be done. Anything that boils down to matters of taste. Or stuff that is not capable of being true or false. But it also can help if you know for yourself why you think something is right or wrong.
At the very least you might get a buffer against snake oil merchants. Be they political or ideological. If all they have is faulty formal arguments, they are most likely very wrong. People are harder. Because people lie. A lot. Some even do it on purpose.
The most common "lie" here on itch is, that people think they are game developers. This is more exagerration than lie, but it is the self publishing thing. Are self published writers really writers? Are youtubers actors and directors? Technically, maybe. But there is a difference between amateur and professional. But who would honestly call themselves an amateur game developer ;-)
it will be even less tolerated
Most adults are insufferable in their idiosyncracies. Just look at me and my overly long texts. And the ones you suffer, you just did not look hard enough or just do not care anymore, so you suffer them in silence. The problem with the internet is, that people have lower barriers to be inpolite. and some are just mean for the lulz.
The pandemic exposed lots of disturbing people. You would never have considered them to be like that. But in happy sunshine times, you do not see how people really are. The amount of stupidity is frighteningly high among "adults".
I want to talk about something personal that is not so much related to Harmful Heaven
That is not advised. You can of course set up a blog or something and link to it on your profile and even game page. Which would give you even more freedom, because a lot of things are out of place in the community here.
If you have thoughts about certain topics, you should search for forums dealing with those topics to exchange with like minded people. The community here is for indie and hobby games. Talking about other stuff is rather discouraged and people might react alienated or not at all. If google fails you, look at reddit. There is a subreddit for just about anyhting.
The creative expression of choice here, is of course, making a game about it.
But tl;dr, Do not listen too closely to strangers on the internet.
