What pisses me off is when anyone tries to tell other people what and how to eat, as if there was a magic diet. Doesn't matter if you're a vegetarian, vegan, primal paleo fan, Atkins enthusiast, pescetarian, halal/kosher follower, Epic Meal Time bacon junky, people need to realise that everyone is different, everyone's dietary needs are different, and with the abundance of choice as consumers right now, we have the ability to pick and choose. We're not cavemen anymore, we have developed into critical thinkers, able to understand our biological processes, analyse them and apply thought to our dietary habits. Still, meat eaters get extremely defensive when it comes to that meat. All of a sudden, we vegetarians are disobeying nature, going against some design, living in some delusion. This is usually a double standard, because these people don't expect us to also move out on the savannah or climb up trees or fight each other in small bands and hunt with spears (well, some of these people really like fighting in small primal bands, but that's not the point). We have evolved in such a way that we are now capable of choosing when to simply obey our instincts and when to apply rational thought and/or emotion. And this is part of nature. We haven't separated from nature by becoming critical thinkers able to influence our environment and nullify natural selection - it's a part of natural selection. Those abilities made us populate this entire globe, we should celebrate them instead of continously arguing for reverting into a more primal state.
As for vegetarianism being unhealthy, nice of you to link some random blog krellin, here are some of my links:

"In prospective studies of adults, compared to nonvegetarian eating patterns, vegetarian-style eating
patterns have been associated with improved health
outcomes—lower levels of obesity, a reduced risk
of cardiovascular disease, and lower total mortality.
Several clinical trials have documented that vegetarian eating patterns lower blood pressure. "

"It is the position of the American Dietetic Association that appropriately planned vegetarian diets, including total vegetarian or vegan diets, are healthful, nutritionally adequate, and may provide health benefits in the prevention and treatment of certain diseases. Well-planned vegetarian diets are appropriate for individuals during all stages of the life cycle, including pregnancy, lactation, infancy, childhood, and adolescence, and for athletes."

Some great guidelines from the Dietitians of Canada for vegetarian diets.

"We examined the records of 8179 men and women aged 30 years, whose IQ had been tested at the age of ten. Twenty years on, 366 (4.5 per cent) of participants said they were vegetarian. Of these, 9 (2.5 per cent) were vegan and 123 (33.6 per cent) stated they were vegetarian but reported eating fish or chicken,' says Dr Gale.
'Those who were vegetarian by the age of 30 had scored five IQ points above average at the age of ten. This can be partly accounted for by better education and higher occupational social class, but it remained statistically significant after adjusting for these factors."

The last one was a cheap shot, but I got tired of looking for even more associations and health professionals saying that vegetarianism is healthy. But I guess it's all just ideology... It's a conspiracy!
