I think the supporters are legitimate people that have seen the hardships that the 1/5th have gone through, or have traveled a lot and discovered that we can all be friends, or went to those special global partnershipish colleges where all cultures are equally respected and where only extremely decent and promising students study. And they are blinded by that. Unfortunately the people hoarding the borders probably didnt go to such colleges and they dont want to be friends and on top of that majority of them were never really in suffering to begin with.
