I agree with alot of what you wrote, but I think alot of ideas from the LEFT, not entirely sure what you mean by that, get struck down because there isn't anyone on here to defend them. It would be like going to a liberal site and having one of them say that alot of conservative ideas are consistently struck down there. This site, like so many others isn't really about debate or searching for the truth, its getting together with people of like mind to discuss issues, and, more often than not, hear what you want to hear.
When I say ideas from the left, I mean things such as government spending. Not many here like the spending being done by our "conservative" president but I think we're all willing to give him a second chance.
There's no end to people coming here to "enlighten" the Luddites here, but it's really not necessary.
There are more than enough people here to debate with reasonably and civilly.
So what if they are set in their beliefs and not easily swayed?
