Because we, as a society, allow people to do things that we don't like. We aren't usually very good at it, but when you consider that it affords people the luxuries of doing things that others might not approve of, like having a relationship or marriage with a member of the same sex, or creating video games with unpopular themes, or creating rap music, or burning the American flag, etc. If we only allowed people to do the things that everyone approved of, we wouldn't actually allow people to do very much at all. Freedom, art, society, and speech would all suffer.
