My biggest gripe with the militant vegans/zealots is that a vegan diet is suboptimal for health, and that they want to impose their preferences on other people through policies such as taxation on (healthy cuts of) meat. A green MP here recently said X meat is cheaper than vegetables/fruit and "that's just wrong!", omitting the fact that the meat she was referring to was made out of mechanically separated meat (the kind pet food is made of) and is beneficial in preventing waste. The vast majority of vegetables are way, way cheaper than meat.
I recall seeing vegan propaganda in primary school, supposedly humans are meant to be plant eaters, here's a picture of herbivore and carnivore intestine tracts! Anyone that's thought about this critically, should know that it's bunk and the data they use to show that veganism is great for health is cherry picked.
I was vegan for a few months and vegetarian for 3+ years in uni. The reason being I wasn't training when I was vegan and I wasn't barbell training when I was a vegetarian and there are legitimate environmental and animal welfare issues for it.
You just can't get enough protein to be strong (recover from resistance training) with a vegan diet. And anyone that's looked at the leucine content of a slice bread (0,11g per 35g) and that of a any cut of lean meat (2,5-3g per 100g) knows why. The vegan propaganda in this regard (game changers film) pisses me off. None of the "vegan athletes" got big and strong with a vegan diet (they switched to it after being meat eaters that got them there) and they don't show they're eating a metric shit ton of concentrated plant protein to meet their protein requirements. Also none of those supposed athletes are competitive at anything.
Animal products are healthy. They're incredibly nutrient dense, contain vitamin B12, vitamin D, A and omega 3 fatty acids (the latter 2 which can be produced by the body but not in optimal amounts for everyone).
Humans are meant to eat animals and can survive on a vegan diet. Any study comparing vegans vs omnivores isn't taking into consideration veganism is a dietary intervention.
We know that being strong and resistance training is important for health, so telling a 70 year old they should eat less meat when their protein requirements are quite high is a harmful thing to do.
High intake of soy can literally make men impotent and give them tits. There's really no way to get 150-200g of protein without going through a jar of plant protein every week.
A healthy diet contains fatty fish once a week, organ meat a few times a year, occasional or daily eggs and dairy, and a small cut of white meat. Militant vegans that want other people to sacrifice health in order to "save the planet" can feck off.
