I've looked at the_donald a few times to escape my own filter bubble and it's very much censored - stuff like Trump's recent reneging on the persecution of Clinton didn't appear at all, and comments calling out Trump's lie about having saved that Ford factory from relocation to Mexico were promptly deleted. It's in their rules and that's part of the package, it's extremely controlled.

Use uneddit.com on the_donald if you want to laugh.

The_Donald is called "The_Donald" not "politics". "politics" shouldn't have the exact same problems as "The_Donald".

That was the whole point of The_Donald – to protest the perceived abuses of other subs by doing the same thing more blatantly.

That's what they mean when say they're a "free speech" subreddit: they're protesting against restrictions on free speech, they aren't providing a place for free speech.
