you are a reasonable person, so please don't take what i am about to say as flaming...but i must comment about the part of your post i have highlighted.
no, you don's HAVE to get in peoples' faces, you CHOOSE to get into peoples' faces. there is free will and what you are saying is, i can't get enough people to agree with me, so i must resort to any tactics that i think will work. (note- my use of the word "must" is theirs not mine) whether protesting out in a field would work or not depends upon YOU making your case, and these wet-behind-the-ears 60s wannabes have not made it.
and please don't confuse the fact that we may see more of these with most people agreeing with them. they do not represent the majority or even a sizable minority. this may be the tip of the iceberg as you call it, precisely because these nuts are such a small minority that they will become increasingly frustrated as their protests continually fall on deaf ears.
