That is exactly the whole point here. You don't have to agree with everyone's opinion, nor is it your place to judge anyone for having one. This is the exact reason why we have freedom of speech: so that everyone can say what they think and have their voice heard, and have it respected. If you don't like that someone has a different opinion than yours, then you are free to ignore that person or their opinion. You cannot force people to agree with you and nor should you try. It may be true that this place can be a bit "rough" at times, but the idea is to keep it democratized.
