Again, it is clear that any group who wanted to create a scene and blame it on another group can send in groups to do this. I have seen it, and have given examples of when that happens.Its clear what happened!!! You can continue being disengenous if it makes you feel better....
It would be better if you merely said, yup it was bad behavyor instead of defending this stuff!
I also do not believe you have any evidence other than the fact that they were against the bill that these people were republicans. I reject their sentiment, and am glad that not all of the protesters were even close to shouting that epithet.
