... I left a local forum due to liberal infiltration, and was having really bad temper tantrums because of their sinister way of looking at life ...
Welcome! The first politics & news board I was on went from full conservative to full liberal, though the transition happened a few years after I had moved on. I feel like I need a shower after visiting such places. Sinister ... an interesting word choice. People pretty much filter everything through whatever world view they have - myself included, of course - but politically-oriented libs and progs have a very narrow, doctrinaire, bitter, angry, cynical filter, and they force everything through it, no matter how poor the fit, no matter how much they have to twist and mangle what they force through. "Narrow", "doctrinaire", "bitter", "angry", "cynical" and "sinister" all catch aspects of the mindset, but the wordsmith in me wants to find the one, perfect, all-encompassing adjective to describe the mindset.
