It's also sad to see how people on either side of the debate on basically any issue what so ever are becoming more and more intrenched in their ideologies. It used to be that people were right wing or left wing. Now you have ideologies about everything, a cell phone you use, a car you drive, the type of food you eat or don't eat.
With grater availability of free expression that can reach many people, the arguments that used to be civil and intelligent quickly devolve nowadays into shouting matches, where the messages shouted are the most extreme, and often the most idiotic, version of any given side's message.
It's true on any board nowadays, even something like HN. It's very sad to see well meaning and intelligent people devolve to this, especially considering how ineffectual the actual messages people are shouting are.
I generally try to form my own opinion about things. Which basically means that my views are generally hated by both sides in this increasingly polarized society. To the left I am a bigot and to the right I am a morally deprived tree hugging liberal.
Not sure if comments are to blame exclusively though. Perhaps another lesson to take out if it would be the quote from one of the cinematic masterpiece of this century, Harold and Kumar: "There is no reason to get riled up every time a bunch of idiots give you a hard time. In the end the universe tends to unfold as it should."
