Because they do not believe in the right to assembily
Could you please stop telling other people what they believe. You make yourself look ridiculous.
Wasn't it just a short time ago that the "right to assembly" was mocked when the Tea Party assembled?? remenber all the cnutty whining about that?
I know you are not comparing the tea party to the protest going on by teachers, firefighters and policemen.
It is not about 'right to assembly" but right of public workers. Without unions they have no one to bargain for them and their jobs.
