Hmmm... the extremists are always a problem... ranging from animal rights and anti-testing groups through to civilian armies and terrorists. You will always encounter that small dark group of humanity that go a few steps beyond the normal actions of others and enter th terrority of violence, anti-social behavior, fear inducement etc.
The problem I have is that I can kind of understand why. I strongly disagree with harming others, with labeling, hounding, stalking, shooting, blowing things up etc..... yet when you have tried for so long to be heard, treated with respect, or feel so strongly about something and nothing is done... well, you either quit the campaign, or take it in a different direction.
Inmclude egotistical people, or those with ulterior motives, and you end up with those core groups that do the wrong things... but probably for the right reasons! (As far as they are concerned the reasons are good, for others they may not be!)
The problem seems to be drawing the lines between perspectives, aknowledgement, inacting upon problems and producing results that satisfy all involved.
As an example....
You go to your club to train... have done for years...every time you park up, get out, lock up, enter the building, get changed, warm up etc.... you have a solid routine.
All of a sudden, new shops open up locally, and you can't park anymore. No spaces are left. So you ask about new parking, or parking permits, or a simple soloution to the problem. You leave earlier to get a space, and still can'....all the while you are told it is being looked into and will be sorted out to everyones benefit.....1 month, two months, 6 months.... you have resorted to parking 100 meters down the road, and one day you get clamped.... £50 fine...GREAT! So what do you do? You have as much right as anyone else! You have been there for years, yet aren't considered above any of the newer ones...if anything, you are thought less of as you aren't spending £XXX money in the shops!
You then notice these stickers in the new-shoppers cars, permitting them to park during certain times for free!, whilst you have to either park ages away, or pay extortionate amounts for a ticket......
So what would your reactions be?
If you lert it lie, you suffer for no reason! If you take action, most others will see you as an extremist, though some of your fellow club members may support you - be it openly or covertly!
Now take that scenario and switch the details... you home town is invaded, and the other towns ignore you or won't openly support you. Or your pet cat is stolen, and you end up seeing someone wearing it.... your prize car, worth a fortune due to it's rarity is damaged or stolen.... the scenario shouldn't matter, the result shoould be the same!
An odd example... yet considers most of the issues that these people have from their perspective.... once you have answers, take the perspective of the new-shoppers, of the local/original shops, of the new shops etc... it's convoluted and there is no real way to make everyone happy!
The key is getting people to talk and to listen... yet things like money, land, bribes, hate and fear get in the way.... talk falls on deaf ears etc.
Shame, but humans suck in general.
Specifically for the PETA.... most of them seem to be of the ulterior motive group... i.e. violence, general disturbance and little in the way of communicating.... more a fact of the method ofr methods sake rather than ends justify the means, of means justify the end!
