I was/am pretty salty at the Stonehenge stunt, and don't love it when protesters block roadways that often only have consequences for folks already at the bottom rungs (late for work, etc).
With that being said, I can't get my drawers in too big of a wad when a random golf tournament gets interrupted for a few minutes. Honestly, it's mostly funny to me. I'm rather dubious they are moving the ball down the field in terms of advancing their cause. I view it almost like streakers or hecklers; by a large, merely a little bit of old fashioned deviousness. Sure, charge them with trespassing or whatever, and make the punishment reasonable enough to not encourage folks to do it.
