Can you tell someone not to cuss on your social media posts?

Cole

The other day a friend posted on Facebook asking her friends to not cuss on any of her posts. I didn’t think much of it until several people pointed out that they have freedom of speech and if it bothers her that much she shouldn’t even be friends with them.

I was wondering what you all thought. Should you be able to tell someone not to cuss on your posts, or should you unfollow them?
