YABU
As an ex vegan (and ex long term vegetarian) who once felt the same. I found veganizm incredible in the short term I think it isn't without its problems.
I do think everyone should eat more vegan and drastically reduce our meat and dairy consumption.
I do believe we need to source meat from small local organic farms with high levels of animal welfare.
A lot of ex vegans I know look incredible after stopping, they're stronger and the just glow.
I believe/ have read somewhere that somebody types cope with it more than others.
I have always been a healthy eater but when I'm vegetarian even, my skin goes a funny colour and I have much less energy. I know others the same.
I have very debilitating IBS I am intolerant to most pulses, stone fruits, large quantities of most vegetables, many fruits, all gourds, many nuts, soya products. I am on low fodmap (my intolerance diet) for vegans group and it's rife with very disordered eating.
I would love to be vegan, I am squeamish about animal products but I eat them now because I cannot actually parent particularly well when I'm exhausted and can't leave the toilet.
I also think a lot of the stick meat gets health wise is looking at crazy big factory farming/ herd operations and not smaller organic farms.
If everyone ate 80% vegan it would have a bigger impact than say, 40% eating perfectly vegan.
I think a lot of vegan materials are bad for the environment and no biodegrade. There are awesome things like hemp (cotton too but that needs a lot of water) Second hand fur and leathers are at least biodegradable. Also we have enough clothes on the planet already so we don't need any new ones but everyone should be able to wear the ones that already exist (iyswim)
Sorry rant over. Merry Christmas!
