You mean the tea party groups are so powerless they are incapable of policing their own functions and handling counterprotesters and nutbars who show up? I don't buy it. Either they are a powerful movement and equal to their opposition or they're not. Either they are determined to get their message across and willing take responsibility for doing so or they're not. Blaming others for every hitch and demanding the right to speak without opposition is a cop out. That's politics. It's also the nature of free speech. The "free" part is a misnomer, there are always consequences for good or ill and it always takes more than just showing up to be effective - especially when both sides have the exact same rights.
Apparently so...look at what's happening.
And like I said, I know it's a tough job under the circumstances. But if you're going to throw a party then you need to think about how to deal with the gate crashers - and that means all of them, not just the ones on the side you don't like. That whole personal responsibility thing again, it keeps biting all kinds of people in the ass.
But again, the average person showing up at a rally isn't responsible for all that, it's the organizers who are failing them by not doing their homework, looking ahead and having the strategy in place. Easily solved if they want to, and some groups don't seem to have these problems so I would assume they have solved it. A pow wow on tactical strategery might be in order. Just food for thought.
