Who said I wasn't having fun? My fun involves cycling, motorcycling, snowboarding, beach volleyball, camping and hiking. My enjoyment of life is not centric on "being able" to eat certain foods.
Glad you think I'm a waste of existence.
Everything is permitted, sure, but that includes the demise of the human race. We serve no benefit to this planet. In the very least, to extend human existence, we should learn how to manage resources better, and part of that is not using extreme amounts of resources to provide a food source that is, actually, detrimental to our health.
Don't, something something logic, something something something science.
