I hate about 90% of all vegans, "most" of them are annoying as hell and think they're Superior to everyone else because they "save" the environment, not saying they are all like that but most of them I have met are. Also they do realize that in order to plant wheat and vegetables you have to cut down tree's/forests and tear up the earth in the fields in order to till the land and make it ready to seed and plant right? also vegetation absorbs carbon dioxide from the environment which is toxic to humans, eating up more vegetation technically leaves less of it to absorb it also eating a lot of vegetation causes you to emit methane gas which is harmful to the environment.
Also being vegan isn't that healthy for you actually, not as much as they think it is. The only way to be truly healthy is eating a balance and healthy intake of food that includes vegetables, dairy, fish, fruit, nuts, wheat's/grains and meat.
Also wild game hunted in the wild is actually far more healthy then any vegetable you can eat due to all the herbs and vegetation the animal eats and those nutrients are absorbed into the meat, this has been proven by a nutritional standpoint to be healthier then any one vegetable and very healthy when eaten with a balanced intake of food from all food groups, the meat is also incredibly lean with low fat content.
Also if you vegans truly cared about the environment then you wouldn't drive cars which emit pollution, you wouldn't buy or build houses or furniture which use up lumber taken from forests, you wouldn't use technology which in general it's production has negative effect on the environment due to pollution from factories you also have to be careful because technology is not easy to get rid of (throw away) in a safe manner also you do realize that when you eat vegetables your literally eating decomposed animals carcasses and shit right? we have a saying in Kansas when driving around in the countryside when you smell shit you take in a big whiff and say ah smells like money, you wanna know why? because the farmers use the cow crap from their herds as fertilizer for their crops because it makes the earth fertile and easier to grow stuff in.
Also those big buff vegan bodybuilders and fitness guys you see promoting veganism I guarantee you they are either taking drugs, steroids, whey protein powder directive from eggs and or supplements or are eating meat in secret.
