Dennis please show me examples where right wingers on campus have done any of the following to prevent invited speakers from being heard:
- pulled fire alarms
- made anonymous threats so the U will cancel the event
- thrown gasoline bombs
- stood in the room and continuously blown whistles
- held violent protests that speakers had to get by to enter the venue
- grabbed people and beaten them
- threatened the speaker

And please show me examples of the right doing things such as occurred on April 15:
- dragged people into their lines and gave them a beating 5 or 6 on 1
- thrown M80's, bricks and glass bottles into a crowd
- dismissed senior citizens thrown to the ground as "hey revolution is dangerous"
- gathered together, to silence, speech wearing uniforms(!) designed to conceal their identity

You won't because you can't.
You need to admit that, if not to me then at least to yourself. And once you've admitted it you need to suppress the urge to rationalize why it is ok.
