That is my favorite argument to use with liberal co-workers: "So the Chicks are allowed to disagree with the President, but I'm not allowed to disagree with the Chicks? The Chicks can try to make the President lose his job (2004 election), but I'm the bad guy for wanting the Chicks to lose theirs?"
The thing is, leftists believe they should be allowed to have the stage and say their part and only hear applause. If someone in turn has a criticism abotu THEM, it's an attempt to silence them. Like anyone could silence a leftist.
Conservatives, and especially church goers, are only allowed to have dissenting opinions if they keep them to themselves and NEVER express them in public.
