Everyone has their opinions and because the internet was made to express them, it offers a lot and I mean A LOT of idiots a forum to say what they want to say because in real life, they probably don't have anyone to talk to. Certainly no one that wants to listen to what they blather on and on about. This is their outlet and they most likely think that what they are saying is highly intelligent. The internet is both a blessing and a curse. I usually don't read other sites comments for the very reason you stated.
