Can you discuss something that has meaning instead of just picking?
A few of your comments -
Related to personal responsibility - your words -
"Do you expect things to be calm when nazis want to march in a black neighborhood? What if it was a Jewish neighborhood? What if I got a group together and marched in a muslim neighborhood?"
"What do you suggest? Jailing blacks so that the nazis can't incite them?"
This appears to me that you are assuming that blacks lack the ability or responsibility to behave civily. Did you expect riots in DC today? As far as I know the few Nazis never even marched.
I expect better. Apparently you do not.
And "Skinheads" and Nazis and Nation of Islam and PFLAG and the VFW and everyone else still have the right to assemble. And the rest of us still have the responsibility to allow them to - regardless of the color of our skin or how much we dislike what they have to say.
