Self preservation

1688: 

Most people are unwilling to step so boldly away from convention by taking up a vegan lifestyle, especially if it means giving up their favourite foods. At best, they are afraid of living for the rest of their lives on (and suffering ‘deficiency’ from) a plant-based diet. At worst, they are in ‘atrocity-denial’ - ignoring what's being done to animals by the food industry. Either way, through fear or indifference, they’re playing dangerous mind games with themselves.

Maybe they do realize the truth of what vegans are saying but find that it's inconsistent with their lifestyle. This is psychologically uncomfortable so they do their best to ignore us. They may be afraid of an arising fashion, that if a break-through were made in the public’s acceptance of Animal Rights, it would spell the end of animal farming. That would mean no more meat and none of the thousands of animal-based commodities widely available today. In foreseeing this, people are inclined to vigorously defend their lifestyle and do whatever is necessary to guarantee supplies of their favourite foods. More importantly, they’ll resist everything we are saying about 'the atrocity', which is probably why people pre-emptively shy away from discussing with us anything to do with animals that are used for food.
