I remember when /r/politics was full of conservatives, right-wingers, the tea party, what have you. People would ask them to elaborate on their position, ask for references, or point out the flaws in their logic. The response? Moving the goalpost. Or "both sides do it." After a while, I ignored them because it wasn't worth my time to debate them. We won in a way; conservatives eventually stopped bothering to comment in /r/politics and retreated to their safe spaces.
