There's tens of millions of well-armed Americans who'd rather die fighting then let anyone take away their right to eat red meat, so good luck trying.
- healthier
- tasty
- cheaper
- a small contribution to keeping the planet livable for their children
- as a sign of respect for $DEITY/the planet/...
Many people will see some sense in at least one of the above arguments at one point in life.
I would never argue for banning red meat as it will certainly backfire and end up counterproductive.
