We can't confuse the right to speak with the right to be heard.

You can post and say anything you like on steem, but that doesn't give someone the right to be heard by everyone. I think that's a reasonable compromise.

If someone is saying something that a lot of people disagree with, the flags don't delete the post. The followers can still see the content if they so wish.

As someone who was flagged down to -5, I can say that my content wasn't "censored", it just wasn't as visible.
