The worst thing about this meme/chainletter/whatever-thing is, that it shows that something is quite wrong with our society (hah, as if we didn't know). If a thing that should be quite natural and a matter of course is discussed so fiercely, there is /always/ something wrong. No sane person would admit to be against (for instance) women's rights, either. You wouldn't need to post some five lines written by anyone else there to prove that women's rights are something you firmly believe in. People would be surprised (at least) to see you saying something against it.
I tend to ignore these chainletters anyway, beacause I have no idea what people who so busily try to talk a guilty conscience into you to make you pass their mails on without gaining anything (at first sight) get out of all this. There must be any gain, otherwise they wouldn't do it. Things like that wake my suspicion.
