Creating a list of domains that have opposing perspectives

I'm looking to build a list of websites that focus on a subject about which people have a strong opinion. But for a particular subject, there will also be sites with very different perspective... I want those also in a group. So for example, liberal sites and conservative ones, religious and atheist, public education and home schooling. Often there are two opposing views and sometimes, there may be 3 or 4 views or even substantial sites. What I would NOT want is say for religion as a subject, catholic, jewish, hindu... they are not opposing, just different flavors. Vegetarian and meat eaters are opposing. The output of your work is a spreadsheet column list of the domain, a 1-2 word description of the focus of the site and the full URL (HTTP://[login to view URL]) So Like this: Democratic [login to view URL] republican [login to view URL] I want only the main domain name, American sites in English and sites that are not offensive disgusting and otherwise socially unacceptable. Something if left up on someones PC would not impact a child negatively. Mainstream domains also are preferred. For example, No sites about guns, drugs, sexuality, hacking ... nudity, murder etc etc ... I'm looking for 100 sites in groups of no more than 4 sites per general subject.. I'm also interested in you coming up with the other categories. I've listed a few here but to fill the 100 sites, we probably need a few dozen more. I'm interested in working with USA respondents who understand USA culture.
