Why Idiots Infest a Fat-Acceptance Newsgroup

In my adventures on the groups of Usenet, I consider my home group soc.support.fat-acceptance. I very seldom post from other groups, even though responses have been cross posted according to the idiot heaving the insult to which I wish to respond. In this group, troublemakers called "trolls" deliberately post things that make the regular posters angry or upset in some other way. I have always suspected that, while there have been relatively few posters that defend the right of fat people to exist without obsessing about diets or gym memberships, there was many people who read without posting. These people are called "lurkers." I suspect that most of these lurkers are overweight people who have internalized the stereotypes aimed at fat people. You know the ones:

Fat people are morally bankrupt.
Fat people have poor hygiene.
Fat people are lazy.
Fat people are gluttons.
Fat people are slobs.
No one can really love a fat person. Use them and throw them away.
Fat people have no sense of self-control.

The list is endless...

Why do supposedly law-abiding individual people, who would never be disrespectful to another person in real life, who conform to what society demands of them, hide their identity using anonymous remailers, then say and do such ugly things?

Please tell me what you think of the following comments:

1. "His name is Mr. .357. He loves you. He will never argue with you. He will take your pain away. Instantly. Waddle to the shower. Flop all the bacon lard to the side. Stick Mr. .357 up your hairy nose. Squeeze...don't pull. BWAM!! Now you'll feel better. We'll feel better. The maid won't. The soap factory people are smiling. I'm laughing so hard my ribs are aching. BWAM! BWAM! BWAM!"
2. "The good guys have seen your credit report. Your work history and your medical history on my website. (at the end of this drivel he writes) Now get down to the bottom of the boar vat where you belong until I decide to (expletive) in your face again cow(expletive)"
3. Defamation of character is common with these cowards: "Actually, she (me) is a confirmed lesbian (I am not gay) who frequents the dyke bars in the Dallas (Texas) area. She got kicked out of the service because she was found out." (that is a lie as well.)
4. "I'm calling (my my client) tomorrow. If she still works there, she is in (expletive) for sending abusive emails. (I insulted his manhood) ... I have their toll-free number from their website right in front of me."
5. "Blobbi I'm sorry already. That you like having sex with boars. Save the boars. I am sorry Blobbi is entertaining her animals right now. Please call back."
6. One idiot in particular started writing bestiality pornography with me as the subject. He was saying that I was having sex with pigs. I warned him that I was going to turn him and I did in 2004. He has been harassing me ever since.

All I can say is that if you think this is acceptable behavior to display against someone who objects to ridicule and stereotyping, there is something wrong with your thought processes.

I am no angel. I have used off-color language to describe what I think of these so-called people. However I can say that I have done none of the things I am accused of and will fight it to the end.

Stay tuned-there is more-a lot more.
