Well first let me say, I've never played in a LARP and doubt I ever will, simply because it doesnt interest me.
I find it interesting all the people on both sides who yell about tolerance of there group, but dont seem for tolerance of people voicing there feelings. As long as no one is saying that ALL Larpers, or tabletopers, or whoever, are nuts, I dont see a problem. If all your experiences have been bad and you feel that a large part of one side or the other are nuts, thats perfectly valid.
Although I do agree with those who have said that simply because its a larger and less well controlled group, LARPs are probably more likely to have larger numbers of undesirables than most tabletop games..especialy since most tabletop gamers play predominantly with people they've known a while and such.
But the fundemental truth remains that there are going to be undesirables in any group of people.
I dont really see anyone on this thread doing to LARPers what most "norms" do to we gamers as a whole. Especialy since most of those who have exppressed negative feelings try to do them in a balanced way, and base them on experience, which isnt the case with most "normals" who bash RPers and gamers as a whole.
