No comment by anyone proves anyone is a liberal or conservative. No comment anyone posts proves anyone is anything. That's the nature of the site.
The user raises concern that a right leaning forum has right leaning filters but fails to mention you see that with some left leaning forums. Based on the shock this person has never visited a left subreddit. Does that mean he is right leaning? Or does this person seek out a right subreddit because they are doing research?
I would guess research because the shock tells us he doesn't visit these places often and he doesn't visit more conservative places lile truth social because they censor at a higher rate.
There is my reasoning. You're challenge is to disprove this.
No one knows anything. Everything is an educated guess.
I gave my best answer with logical points. What is yours? This is a process law enforcement goes through when moving from unknown to known. I like my theory but I am open to others that may conflict.
I don't say things like "you are not X" when I do not know whether a person is in fact X or not.
I read all the same comments you did, and i didn't reach any particular conclusion about the person's politics. Your case is incredibly contrived, imo. A conservative who attempts to use a conservative forum and has a bad experience would have every right to talk about it. Why wouldn't they?
I am making a guess based on the opinions presented.
The point here being that it is hardly relevant how a subreddit specifically and explicitely for conservatives is moderated, when we are talking how mainstream subreddits are censoring conservative opinions.
Many grievances appear to be liberals concerning themselves with how /r/conservative is moderated, most likely after being banned for astroturfing there.
