There are studies showing the correlation between meat consumption and cancer, and there are physicians (in the US!) advocating how a raw diet helped cure cancer in their patient, supported by the famous
China Study. However, I don't go around lecturing people who speak about meat on forum posting scary pictures of slaughter houses or nasty diseases.
There are people dying of cancer who haven't ever smoked a cigarette, there are people who lived a century even smoking a pack a day. By an ignorant standpoint, I'd say "better without it", by a human standpoint, I say life is too short to be scared of everything.
