Not the same kind of suppression, not by a long stretch.

You're still legally entitled to stand on a street corner in the US and shout racial slurs, if that's your thing. You're also legally entitled to assemble and protest there.

None of the undertakings that are equivalent to those actions are permitted in China, and will immediately subject you to violence.

Yeah, I don't know how America can be considered a so-called "free country" when the people living there will get angry at me for using slurs and being generally discriminative. I'm sure it's just a matter of time until they create some kind of unethical legal punishment too, as they did with expressions of anger (assault, murder, etc.).
