I'm not vegetarian whatsoever but I've wondered if people of the future will judge people today for simply eating meat since they have artificial meat and all that.

For example, slavery in Roman Empire was accepted as an obvious thing. There were people who advocated treating them better and even encouraged freeing them but altogether abolishing it was simply unthinkable. Not even by Christians. Yet some leftists think certain American historical figures are utterly irredeemable for that.
