The simplest way to look at it is that we're all entitled to the right to feel entitled to something. Doesn't mean we really are, but the fact is that folks are going to feel the way they do. In certain situations, like this one, it's a sign of ignorance and spoiled attitudes, but they have that right to be that way. It's no different than your reaction of ranting/crying about their ranting/crying. Just do as can be found on the internet in general: mock them in the relevant discussion and move on.
