One word Sly. Innitiation. This should be directed to the ones that inntiate the conflicts. Id be happy to point those out to you if you like. You cant expect people to just allow others to push and shove without shoving back. The forum protects HCPs antics far too much and anytime it seems he is doing wrong, then there is a general comment to all, but hardly ever directed at him in any type of serious manner.
If people didn't try so hard to CREATE conflict by actively trying to mess with people they consciously know have issues with them there wouldn't be so many issues - and you you need to address this with them; Not the ones who push back. Its only natural and human to push back when you are getting pushed anyhow.
I know for me, if I would have read more people telling HCP to back off, I wouldn't post half the shit I do, but since know one else stands up for those he tries to shove around, I do. I also get it may be annoying to some, but then those who are annoyed, again, should look at who is typically initiating these conflicts. Not the ones retaliating.
Two wrongs do not make a right, but damn man, its human nature to defend ones self when feeling attacked. This should be taken into account when lecturing those involved in these conflicts.
