Using your analogy it is more like a dog that bites when it is petted because it was abused in the past. The owner, the reasonable part of Variform, has notified others of this dogs limitations and the issues invovled so that others may act accordingly with the dog. Some people choose to interact with the dog and get bitten but realize that is the risk they took but some people interact and get bitten and then react to the dog in a negative fashion futher introducing issues with the dog. The dog becomes even less trusting and more violent.
You seem to want to empathize SO much with the lost and hurt and suffering that you're forgetting this is not a hospital or a therapy room. This is a place where adults get together to hopefully relate in productive ways to each other, and adults adjust to each other in order to enable the most effective communication.
Again, it doesn't matter WHY the dog is biting people in terms of where you let him roam. Even if the dog was abused as a puppy, if he is going to bite people and does not respond to correction, you do not put him in the day care with the kids or free on the street. What you do is get him to an environment that will both protect him from others as well as protect them from him, and maybe offer the possibility of slow change.
I suffer seeing this and I am feel a loss when the dog finnally gets kicked to the curb because I was interacting with the dog in a healthy and productive way and felt that eventually the dog would have learned to trust someone.
If you would like to be Variform's friend and even invite him to stay with you at your house, you have that option. You have a good heart and apparently a lot of patience and the capability to suffer/ignore abuse. So you are free to befriend who you wish. But you don't get to decide how the entire community must respond. Note that why you are fretting so much about Variform, you don't seem over-concerned about the people who might have potentially have been wounded or driven off by his behavior. If you want to care about one dog, why aren't you caring for them all? That's why I see your affection here as a form of favoritism.
When Variform notified people of his limitations and abilities to interact appropriatly they saw this as an indication that he planned to do this and enjoyed acting this way or was deliberate etc.. but it did not seem they saw it as the owner notfying you to beware and be gentle.
Again, maybe it can be credited to Variform that he could notify others of this, but it doesn't exonerate him of his choices.
I am in my 40's. I think Variform is as well (isn't he)? I've suffered a lot of emotional abuse from family and religious groups over the years. There are behaviors of Variform's that I could identify with -- some ways he would talk about things that I could see in me, or did see in me in the past. But I made choices to not lash out at other people needlessly and try my best to respect them even when they hurt me or disagree with me; he has long made other choices and even when challenged, continued in that vein. I see him being where he is in part because he withdrew into himself, closed out people on the personal levels, and feels free to judge and criticize and impose his values without real consideration of others. He seems to have his own rules for himself and then the rules he expected others to follow.
I feel as if the people in the forum, do to their inablity to handle such individuals as Variform, have made his issues become someting more than they needed to be. I suppose I have to accept the results of this... but I still cannot help but feel like things could have been different for Variform if we had handled them better.
I am not sure how more reasonable people could have been with someone like that. Maybe this just wasn't the right environment for him. Again, this is not a therapy room centered about Variform, it's a discussion forum where there needs to be a modicum of give and take from everyone involved... including people like him. Maybe if everyone on this forum wanted to take him under their wings as their pet project, it could have worked... but that's not what this forum is about. It was pretty basic: he simply needed to stop attacking people (vs the argument) and yelling on soapboxes and actually engage in a discussion where he was open to learning something. The bar is pretty low. The huge majority of people do not get banned.
