I think this has been spreading for quite some time. There’s a group called the “English Defence League” which has been doing the same kind of thing in England.

I love this quote from a US rabbi speaking to the EDL in 2010:
“History will be recorded that on this day, read by our children for eternity, one group lit the spark to liberate us from the oppressors of our two governments and the leftist, fifth column, quisling press, and that it was the EDL which started the liberation of England from evil.”
There are other “Defence League” type groups in several European countries.

It’s hard to tell if there’s a similar group in the US. Maybe this:

It looks like English authorities are taking preventative measures. The EDL and their like won’t get in the way of the diversities and their prosperity in the UK.
Pamela Gellar has an article about the arrest and intimidation of 53 people that include the leadership of EDL and BFP party.

People will say these parties are made up of hooligans and KKK-like racists. Generally white people that care do kinda fit the stereotype.
The same could be said of Tea Party or any militia - defend the Constitution types.
Oh yeah - they do say that; it just doesn’t play as well here in the US.
