Thing is though you just explained the thought process of the right. "Everything is black & white. No greys. No exceptions."
"It's the morally right thing to let immigrants cross borders illegaly." - Yeah, but why is the process of applying for asylum at a border entry point illegal anyway? And what are the political actions the US had made that have contributed heavily to the migrant crisis?
"It's morally right to fight companies (while ordering on amazon btw :D)" - Yeah, our issue is with workers rights, tax policy and deregulation, not the business themselves. In the case of the practices of the business itself, boycott and find local business to shop at.
It's moral to quit fossil fuels (while taking the plane to Paris (and ordering on Amazon via air mail) :D). - Yeah, because it's most peoples only choice as it stands. The fact that we already have the technology for renewable energy global transport should be more than enough to push everyone to make the switch, but it hasn't. Until then we cut down on what we do use and find cleaner ways of domestic transport.
Without sounding too douchey, yes I would like to lecture you on the GND, because so far you've provided plenty of reasons why you've been reading the wrong shit.
