I agree mate. It's definitely his choice how he uses his SP but as a community, if we don't agree with someones behaviour and believe it is having a negative effect on the community, as Bernie did in his post here, I think we all have the personal responsibility to let them know we don't agree and that we think they should reconsider their actions for the good of all.
I also agree with you in regard to the second part of your comment. There are a lot of ways of dressing abuse up as something that is good for the 'community' but that simply enable some to share the wealth between themselves more readily while ignoring the vast majority of others on the site. Lots of little 'gangs' forming around the community. :(
Hope your day is going well mate.
