Explain how they prove that wrong? >bullshit claims Like yours? I think maybe you're retarded with words. A car that still drives but has 3 wheels so therefore drives poorly is not functioning. It may drive and get from point A to point B in a rickety manner but that's not functioning. A computer that turns on and plays videos, browses the web, creates documents but is riddled with malware, spyware and ransomware is not functioning. Functioning **does not** simply mean "doing the thing". Functioning **does** mean "doing the intended thing in the manner intended". Vegetarians can't do the latter. e; Also I explained, and you can look this up, what a protein is. A protein contains all 9 essential AAs. ZERO plants offer that. Done. The rest is just an expansion of what happens by the body to adjust to this lack of a necessary macro.
