Here's a little thought experiment. Let's say you're in the store buying groceries, and you come out to the parking lot, load your groceries and small child in the back seat and then hop in the front seat to start the car. Immediately, a couple of protesters came out of nowhere and move their car behind yours, effectively blocking you from leaving the lot and going about your day. Now they're waving their signs, chanting their clever, catchy slogans and parading in circles around your car. This goes on for two hours, the police come and finally they leave and you can drive away with your hysterical toddler and two gallons of melted ice cream in the back. Is this an acceptable way of protesting? If not, why not? Because it seems that many people are OK when this exact thing happens to a hundred or a thousand people trapped in their cars by protesters while on a freeway or bridge. But doesn't it seem wrong, if not criminal, when the protest is limited to one person? Does it make sense that such protesting is OK when it affects a thousand people at once, but its not OK if its just a single person affected? Would love to hear some rational reasons why.
