I'm mainly talking about the people who add nothing to the debate but insults and personal attacks.
I understand frustration with people who seem to not even consider evidence you provide them to support your point, but I still don't see a need to go the insult/personal attack route if they haven't with you. Hey, as soon as someone starts throwing out insults at me, I drop the politeness myself. But as long as they are being civil and debating the topic I try to be civil as well.
Also I think people mistake and disagree on what is "irrefutable evidence".
