The best thing we can do is be patient and hold the line. They will be come violent and defensive action will be required but their violence will destroy them just like it did in the late 60s.
What makes you think they were destroyed?
They are the modern day equvilant of the SA of 1936 fame, “hitlers youth” movement. It grew out of control until Hilter was able to convince people that the only way to order was strong police controls by a new group the SS.
It was successfull on more than one front, the SS wiped out the SA in a blood bath thinning greatly the ranks of the useful idiots when they were no longer useful, and it put Hitler in with dictatorial control of Germany. World War II was the result.
Obama and SEIU are trying to enslave America and will bring about a blood bath for America.
The situation is not the same. In the 60's we did not have an administration that was itself promoting the destruction of our country.
