If you see a group of people describing something you yourself participate in as environmentally and economically destructive, you have to choose a framework in which to process that information. Some options are:

1. Sure it has some, ahem, negative externalities and I am somewhat bad for participating. But all of those people are just as compromised as me and they're only mad because they didn't get in first. I am no worse than them. If anything, I'm at least honest about my position.

2. They are right, I am selfishly participating in something that benefits me at the expense of the world.

The problem with 2 is that acknowledging and wanting to be morally correct forces you to change your behavior. So 1 is an easy pick. But that doesn't imply that it's correct.
