Thread number 15,000 where people commenting on American politics are apparently in need of a remedial political education.
When people poll Americans on their ideology, they divide them into three broad categories: Liberals, Moderates, and Conservatives. Liberals are broadly the left. Moderates are the mushy center. Conservatives are those broadly on the right. There is no secret Leftist option, "liberals" include the leftists. When the vast, vast majority, (like 95%+ of the electorate) sees someone criticizing "the liberals" or "the libs," they are going to think that you are right-wing and are attacking the left.
