Chalk it up as one of many whiny liberal 'progressive' activist blogs that dramatically fail to analyze any argument beyond its superficial value and only then with extreme bias. Combine those failings with vapid writing and authors that seem to subscribe to the SJW hivemind and you've got ThinkProgress.org. Honestly, it feels like a strongly liberal propaganda machine, each article filled with all those wonderful liberal values like pseudoscience worship, fine-tuned racism, and promoting liberal leaders like they're living gods. What utter nonsense, the whole domain.
Best avoided. I'd recommend going anywhere else to read your news. AlterNet or WikiNews are way better options that won't suffocate you in liberal puke.
