The new uniform of the Republican party. Wearers of this uniform tend to also be jack boot wearing thugs.
Brown shirt Republicans are a collection of goons who cannot stand things like civil rights. These people tend to think that they are better and holier than everyone else.

What the Republicans have turned themselves into. Especially at the lower level, brown shirts are a collection of thugs who get quite annoyed at those who oppose monkey boy.
New brown shirts accuse those who don't like monkey boy of everything, from causing bad hair days to treason.
