Vegans have actually researched how their bodies work.
They realise that our entire digestive system works the best when supplied with plantfood.
This is supported by SCIENTIFIC EVIDENCE.
They have also realised that eating meat gives you a HIGHER CHANCE OF GETTING CANCER.
And that drinking milk has been UNDENIABLY LINKED TO BREAST CANCER AND OSTEROPOROSIS.
They are generally fit, healthy looking and aren't fat-asses. There are many vegan atheletes and awesome-looking celebrities so dont give me your mal-nutrition bullshit.
They also sit and laugh at people who sit and preach about how little animals get stuck under harvesting equipment, because the meat and dairy industries are one of the leading contributors to global warming and also ruin the lives of poorer people in countries overun by soya plantations (95% of which are used to feed livestock).
Do some research, THEN argue against veganism, or maybe you can't, because there is no arguement. There is just ignorance.
I'm a vegan, and i actually care about other people which i why i like to let people know that they are killing themselves with a diet they've been brainwashed into believing is good for them by the multi-billion dollar meat and dairy corporations. Sorry for bothering you.
