Deflection is the number one tool in the liberal tool box.
For example when Clinton and his zipper were in trouble, the libs big argument was that Reagan lied this one time to this guy somewhere.
Because Reagan had lied that one time to that guy, then we are hypocrites for complaining that Clinton lied.
Another example is when you say policy x that Obama has is flawed, they scream racist. That way the debate shifts from them having to tell us why policy x is good to us defending against the charge of racism.
I almost feel sorry for them, it must suck to have to try to defend ideas and actions that there is no logical defense for.
It's no wonder sites like DU do not allow anyone to challenge what they believe in. If they have to try to defend their beliefs they end up looking stupid.
