They perceived it as a hipster thing? I thought it was just a thing that girls with iPhones used to post pictures with photoshop filters pre-set on facebook.

My issues is with the idea that the planet is being "ruined" and that we don't "deserve" it. The planet happens to be one of the ones capable of supporting life like ours. No matter what we do, it has a finite life span and a maximum amount of time before it stops being useful for any life form. Our biggest responsibility as an intelligent life form would be to do whatever we could to preserve ours and other species beyond this doomed planet. Maintaining a sustainable Earth is important in the short to medium term, but in the long term none of it matters if we never leave the planet. It is extremely unlikely that humans will last long enough and co-operate strongly enough for us to ever actually leave and colonize space, but I can't think of anything more important for us to try.

Also, if we ever were a galactic species, I'd imagine there would be a great deal of strip mining of planets and asteroid belts and things like that. That isn't irresponsible or unethical, it's raw material that should be used by whatever forces choose to use them. It is literally nature.

I'm a bit confused, are you upset that they don't know and appreciate the beauty of math enough or are arguing that math's nature somehow proves the existence of a paranormal force? Or is that what they are arguing? I tend to avoid the reddit atheist spheres because I can only handle being needlessly frustrated so many times a day.
