The "Ban the Hunt" crowd do seem a bit pushy at times....and the "Hunt" crowd feel rather put upon as a result I guess. When you bottle up your emotions and circumstances prevent sane rational discourse by the parties involved then is it any surprise there are not more dangerous encounters between the two groups.
Watching the BBC video's of such protests and encounters should serve to remind folks there are better venue's than have been used to protest. Perhaps it is just too small a piece of land you folks have to share and it lends itself to these obsessions with poking one's nose into other folks activities even when they are legal activities to begin with.
Why not use the legal system or CAA to address some perceived injury or misconduct?
