You can try an experiment for yourself. If you have a Reddit account, comment something on one of these subreddits that doesn't toe the party line. Wait less than 24 hours until your comment is removed and you are banned.
What do you think that proves, though? Yes, they don't let anti-conservative people comment in the sub, that doesn't mean the people that are posting are bots or paid.
It's the same as all the Tesla subreddits, they ban and delete anything negative so casual readers don't get anything but a very biased and curated viewpoint.
Even worse, the subreddit they are using as their example of common "conservative thought" is a subreddit where only verified Conservative users can post, and any dissenting opinion is met with bans and post deletion. You have to go to their Discord and provide enough proof your are conservative (MAGA) before they will let you post.
It's not indicative of how people feel in general. It's a very specific, coaxed and managed image.
I am not lying when I say the front page of the Conservative subreddit is run by less than 10 accounts. You can go there now and see that most of the submissions on the front page of the subreddit is split between the same 3-4 users at any given time.
It's representative of the opinions conservatives share. There are many more commenters than submissions, and other conservative subs like asktrumpsupporters show the same sentiments.
A lot of conservatives in this discussion suddenly seem embarrassed by the side they chose and really want to distance themselves from it.
