  • Do you think being a centrist is code for I am a right winger at heart and share some of their ideals and beliefs with them but I don’t want to admit it to the leftist or the world?

    This is very very simple. The answer is yes. You're so naive you believe factcheck.org. Source: over 3 years ago
