So, Let me get this straight: He is wrong about something?

Prog:  I have no problem with these shady teabagger groups being investigated by the IRS.

Me:  Well, President Obama said he was outraged by it.

Prog: So?

Me: Well, is the President lying about being outraged?

Prog:  Yes.

Boom! The President is a liar.

OR

Prog:  No.

Me:  Is he wrong to be outraged?

Prog:  Yes.

Boom! The President is wrong about something.

Note:  This fantasy is flawed by the fact that progs often take exception to anything the president does that smacks of moderation.  That is to say, when he deviates from their far-left ideology, then and only then is he flawed.
