Conservative Group Trying to Expose "Radical" UCLA Profs

I often wonder why it is that conservatives are so concerned with liberals. I understand that "radicals" are basically considered dangerous to democracy because they're assumed to be communists, anarchists, or some other ists. The funny thing is though, if you look back through US history, it seems like liberals, including many radical ones, have often been the most outspoken voices for democracy and badly needed social change, while conservatives (and many democrats too) have often been willing to sacrifice democracy for corporate benefits and power.

If it weren't for radical liberals, we would still have slavery or at least legalized segregation instead of the covert kind we have now, something liberals are still desperately trying to change despite constant roadblocks by conservatives (e.g. fair housing & housing segregation, segregation in our schools, etc.). We would still not allow women or minorities to vote. We would probably allow big corporations like Wal-Mart, Enron, Nike, and others to exploit and deceive their workers here and abroad without a fight. We would still be working 10 hours a day 6 days a week with basically no workers rights or benefits. Imagine if we had no radical liberals willing to speak out against the threats to democracy, and there are certainly many here, so many so it begs the question of how democratic of a political system we have. Imagine no one pushing for broader understanding and appreciation of diversity. No one trying to get your children health insurance simply because they are human beings and deserve it (oh yeah, that's radical). Who stands to benefit from removing radical liberals? Those in charge of large corporations for sure.
