While you have every right to think someone's shoes are bad, you are not always free to express this thought carelessly with no regard for others. In more common words, you're free to express your opinion, but you're absolutely not free from the consequences of expressing it, and it's unreasonable to expect no consequences ever.

It's a balancing act of reasonability, and some people are indeed bad actors. Like people walking past eachother on the sidewalk, some people are (unreasonably) upset when not everyone gets out of their way. While we're responsible for making reasonable (but not absolute) effort not to bump into eachother, "reasonable" is socially determined. It can feel unsatisfactory without a game-proof absolute rule, but it really does work.
