My grandfather was a cattle rancher. His father was a cattle rancher, etc. When my extended family gets together we eat roast beef because that is our tradition. We eat beef hamburgers and hot dogs at 4th of July cookouts because that is our culture.
Most of the folks telling people like us to stop would never dream of telling another culture how to exist but since we are poor and white we don't really exist since we've been swept under the rug of white privilege.

Luckily, most rational people would probably agree that there is a middle ground between "change nothing" and "eliminate the tradition". For example, cutting beef consumption to once a week or once a month would considerably lower your environmental impact without eliminating a valued tradition.
Aww yeah that sweet nectar of victimhood. There are westerners telling Africans to stop female genital mutilation, should that also be allowed to continue, because, "culture"?
