I think this is a cynical attitude. Until 1990, the majority of people driving cars did not wear a seatbelt.
An even better analogy is tobacco use. In the 1950s and 1960s America, you'd hear the same kind of things about cigarettes as you do these days about meat-eating: it's red-blooded, it's manly, it's good for you! Meanwhile the incredibly high impact to health of people and populations was becoming more clear all the time, just like the consumption on meat.
Attitudes, beliefs, and stupid behaviors can and do change over time.
Changing the world's mind on this is a losing strategy for sustainability.
