I imagine if a core aspect of your lifestyle, work, culture, and traditions were being attacked for "destroying the planet", you may feel defensive and antagonistic as well.

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.
