A vegetarian so extreme that their insistence that others give up meat verges on totalitarian propaganda.
Vegenazis are usually such arrogant douchebags, and come up with the most ridiculous reasons for their vegetarianism, that even other vegetarians want to eat a nice bloody steak after dealing with them.
Vegenazis typically refuse to acknowledge any downsides associated with vegetarianism, and refuse to acknowledge any upsides to eating meat, or will claim anything negative about vegetarianism and positive about meat eating is a conspiracy orchestrated by the meat industry.
VEGETARIAN: EATING MEAT IS WRONG AND UNHEALTHY!
NON-VEGETARIAN: Then why do doctors recommend a balanced diet including meat?
VEGETARIAN: THOSE DOCTORS ARE ON THE MEAT INDUSTRY'S PAYROLL, YOU'RE SO IGNORANT. SEE? MEAT MAKES YOU STUPID.
