What is the difference between Code Pink and the Tea Parties?

Other than their cause, both groups are politically motivated citizens. They both use the same tactics and methods.

edit to add – I do not want to debate the merits of one over the other.

Why is it okay to belittle one group while praising another for the same activites?

Code Pink is marginalized by Fox, the Tea Parties by MSNBC.
Fox praises the Tea Parties, while MSNBC praises Code Pink.

Why aren’t both groups treated equally?
