Wow!
What a short and agro filled membership!
It sounds like the guy has had issues with access by less well intentioned folk in the past.....
I think you're right, and without knowing exactly whats on the land or where those boys camped etc it's impossible to form a true opinion on the situation. He obviously feels very strongly, and no doubt either he or people in his area has had some nasty experiences with people who do not understand the Land Reform act correctly etc. Not too much of a surprise if the OPs mate does that sort of thing.
I feel for him, his post was obviously made in anger, however I wish he had spent perhaps more time reading other posts and how the vast majority of us, especially in Scotland do respect the act, and that many are in fact country people. What ever his problems are or have been I hope he manages to solve them rationally and fairly. Often a quiet word and an explaination to those who break rules etc are better than ranting and raving about it. Teaching them to respect the surroundings rather than give them reason to hate it. Of course there will always be people who intend to do whatever they like regardless of those around them, and to them let the law take it's full course.
