Glad to hear the post struck a chord, or two! :)
Thing is, if a person is genuinely offended by the way a discussion is going (on a message board or in RL), they tend to stay silent (lurk) and perhaps will state their case, but they'll generally back out fairly quietly. What they don't tend to do is stay and labour their point because they know, at least in that group, they're onto a loser. They might go and join in an opposing campaign, where they'll find more sympathy and probably make more headway.
What they don't do is stick around and stir the poop, unless their goal IS to stir poop, to upset, to cause disruption, to try and silence those they disagree with.
I find it amusing how often folks like that try desperately to "lure" people to other discussion boards, occupied by people with opposing views, so they can "duke it out." That's what the MN Hate Group on Bookface seems to be about, and the link that was here the other day to the website where the guy posted a photo of the MN management, I guess thinking it would provoke them to come have a pop at him.
They don't seem to "get" that people might just want to have a constructive discussion about an issue without it taking the shape of a textual bunfight with those who you know won't agree with you on anything.
