Well, you were clearly - and understandably - bothered by the people who offended you by criticising your own food choices, so why do the same to others?
You've obviously has some disappointing experiences at the hands of militant vegans, but that's no reason to assume that all vegans behave similarly, just as I've no reason to assume that all meat eaters are as hostile toward vegans as you appear to be.
Your friend who ended up in hospital for weeks with malnutrition may have been a vegan, but that doesn't indicate a causal relationship - the most common cause of malnutrition is inadequate food intake (due to eating disorders such as anorexia, for example) rather than micronutrient and protein deficiency. In any event, the more significant problem facing the west is malnutrition through over-eating, i.e. taking in more calories than required, and this is likely to be more of a problem for meat eaters than for vegans or vegetarians.
) who won't dig up veg or pick fruit from trees but only eat stuff that has naturally fallen... Each to their own I guess!
