on a global scale more affordable may be true. unfortunately on an individual level in many places it is not. where i am meat is cheaper than the nuts and other vegetables needed to replace it, and those here that can't even afford meat from time to time end up with a rather poor diet.
Plant based diets are:
- more affordable
- better for the environment
- healthier
- avoid/reduce cruelty (livestock and human)
If you want to eat meat, fine, but the comment you replied to is innocuous and not "guilt-tripping" anyone.
