I prefer real-life experience.
I used to eat meat religiously. Upwards of 15 chicken breasts a week, fish, beef etc you name it.
I realised that I'm not more important than the animals, and I saw the way some of them are treated. I changed my ways and honestly I've never felt better and before COVID was in the best shape I've been for 20 years.
You are quite free to eat meat, and for the record, I never levelled at you that you'd brought the manliness argument into it, it's a common thing when people find out you don't eat meat, or your refuse they great big steak the ever-so-manly man has prepared (read: cremated) on the BBQ. But seriously, try it. Give it 6 weeks and see if you don't feel better both physically and morally.
