In any internationally exposed company, Muslims and Mexicans (and other nationalities / religious groups, but these have been the focal points of the Trump campaign) might be your customers. They might even be some of your employees. Now, say you are one of those with said Trump-exploited racial discomfort and you quite often babble about how evil the Muslims are or how nasty those Mexican immigrants are etc. One can certainly infer that one does not really want to put this person anywhere near any job where they might be on a team with actual Muslims or Mexicans, let alone exec type of positions where you may be visiting Muslim/Mexican employees or customers directly.
I really don't care for Marco's attempt to strong-arm YCombinator based on a political candidate (not all Trump supporters are supporting him for the racial discomfort type thing anyways). But I do sometimes wonder whether those holding racial discomfort viewpoints do in fact have a potential barrier to life progress and even whether this sort of thing is a potential contributor to the inequality gap. The challenge to me is how to reduce this without resorting to the often condescending / insulting / I'm-holier-than-thou type responses you frequently see in discussions about this topic.
This piece in Cracked managed to explain a lot of the red state support with genuine understanding. The bottom line is, people lash out when they don't have a voice.

(I'm sorry the headline is just as stupid as all Cracked headlines are. The article is not.)
I also don't understand what everyone have the right to say and mean what they want without having to fear the repercussions is supposed to mean. If someone repeatedly says stupid things, one of the repercussions is that I'm going to start thinking they aren't very thoughtful. Do they have a right to not be judged by me? Or are you referring to some grayer area of repercussions that they should not have to face?
