Your "factual" point is all irrelevant when it doesn't prove to me that I can live healthy and long with it.
The Japanese are proven fact that you can eat meat and live to be the longest on the planet. There is no proof that being vegan lives longer.
And no, Morality is not in the equation. I already said it politely to ask you not to once already. Because if we are talking morals, you would be a massive hypocrite. There is no way you have zero animal products in your home, from clothing, to wallet, to bags, to shoes, to car seats to the steering wheel to the sofa to office chair to the camera strap. Do not bring morality into it, for YOUR sake.
There is my answer then - all absolutely solid facts and you have decided to declare them 'irrelevant' - so you're not going to engage.
It's a very sad time we live in, people choose to ignore facts when they hate what the facts say - we can't continue to debate because you have closed yourself off to reality.
You're also skewing the debate now - now your trying to say plant/meat diets are all with the only target being to live longest - that's irrelevant, ironically, you can die a million other ways before old age, and has nothing to do with the fact we are designed to eat plants - your point is in no way related to what I am saying.
You'll hate me even more for saying it, you don't need meat to live, fact, but you'll just disagree, why do people even bother debating any more, we live in a 'only my way is the right way' society and are closed off to others - even others with the backing of science.
And then to say slaughtering an innocent animal has nothing to do with morality is really quite a sick and disturbing comment - your character disturbs me.
As for your hypocritical point - yes you're absolutely right, I cannot live on this planet without impacting it or 'taking' from it, to sustain myself and what I need to do to exist in a society based on a monetary capitalist system.
Scary times.
PS: I have gone out of my way to not have ANY animal products in my home (thank you for making that point sir !!) - in simple terms I can only try my best - I am sure a man of your intelligence can understand trying ones best vs factual reality. Before I learned about the harm eating meat does, further, the animal abuse and environmental damage I did have such things - instead of throwing them out and buying new (wasteful), I kept items until they wore out - and any replacements I have are plant based only.
Clothing mostly cotton, wallet vegan leather, shoes are vegan cactus (who knew you can make leather from a cactus plant!), bags synthetic materials, car seat is cloth/synthetic - my office chair I made sure also had no animal components - camera strap is neoprene - which I must research now, as I honestly don't know if that's plant based.
I hope you found the latter half of my reply kind of useful rather than attacking.
EDIT: Neoprene isn't animal based, a polymer synthetic - good!
