It is a heated debate in general and well... some things don't change. Not immediately at least. Those who oppose the idea go all-out showing their discomfort, and those who support it are out for blood. And so we get a bunch of jerks, know-it-alls and hypocrites alongside others.
As they say, make the crime, do the time.
Also, are you too surprised by the amount of people here on both sides of the issue? What is this? the fourth thread that is made to discuss this? the first gay thread was fairly reasonable, and it might be open still. But these last ones just devolved into... something.
