Mork, if you're reading this, this is not about you specifically, I want to make a more general point.
You get people come on veg forums and start causing arguments and it's like...are they trolling? or are they really just in need of a little engagement from other vegans to become fully committed to veganism? And where do you draw that line between letting someone discuss veganism in the hope that they transition vs letting people, even meat eaters, come on and stoke divisions and argument to protect the peace of the forum and keep it a happy place. I myself started out coming out to vegan forums with some pro-meat arguments just to see how vegans would respond.
I have a couple of thoughts.
1. Instead of letting people argue and then finally shutting threads down when it gets out of hand, would it make more sense to immediately block a person the second they say vegans are liars or vegan food is disgusting or whatever. But then send them a short message, very polite, explaining that this is a vegan forum for vegans and you need to respect the rules and we'll unlock your account as soon as you read these rules and just confirm you're happy to respect them and make an effort to be polite so we don't lose members? I'm not sure if this is a good idea or not? One issue I can see with it is that it either requires posts to be pre-moderated for a period of time from newbies, rather than instantly appear, or it requires someone to be constantly moderating the forum. (I am not volunteering!) So not sure if it's practical.
2 When I was considering and transitioning, I struggled to find a forum to debate. Either veg forums or nothing else. So if you are genuinely in a meat eater vs vegan phase where you are really open to change, where do you debate? In some ways this forum isn't the right one for that kind of debate, but then where is? Is there another forum we could send people to, perhaps one which some of us even participate in, for meat eater vs vegan debate? And tell people to go there and if and when they are firmly in the vegan camp to then come back to here. Does that make sense? Is that a good idea? And then what would that other forum be, or does someone need to create one?
One vegan forum I know says "Meat eater vs. Vegan debate welcome ". Should we send people there? Of course, if we do, they may just stay there instead of here if and when they become committed to veganism. So I doubt I would do that unless the moderators have encouranged it.
