I wouldn't say cz is a cesspool, rather, consider that the people who visit it most are persons who are ill. CZ posters are therefore, predominantly ill in some way. Your posting seems to suggest that you would expect ill people to behave as normal people behave. I think that's an unrealistic expectation, and instead of cutting them all down as a group by alleging the posters on CZ as comprising a cesspool, one is better off remaining silent on such opinions, since expressing such an opinion only makes the writer appear improper, in my opinion. Kind of like walking through a hospital and telling patients they're stupid because of their beliefs or situation.
Isn't it odd, that people who allegedly espouse "free speech" will piss and moan about others' opinions ? At a fundamental level, thats repugnant to free speech. My view is that I could care less if others ingest herbs or not, and consider it as being none of my business to stick my nose into others affairs.
