I think the left have at the very least caught up with the social conservative right when it comes to dismissing opposing views without much follow-up and discussion (see JoeZhang's comments above for an example).
What makes you think I'm of 'the left'? How much conversation is required when your basic premise is completely wrong ?
You might as well have said "That the moon is made of cheese is widely accepted by many scientists" because that's on about the same level - there is nothing sensible to discuss. That's why I suggested you get a high school textbook not because I was mocking you but because your understanding of the issues is so low it would make sensible conversation impossible without you obtaining a basic education in the sciences.
