IMO as we accumulated more and more "rights", the concept became diluted. We went from the bedrock negative rights of freedom of speech, travel, etc, then to positive rights, and then people started applying the concept of "rights" to what I would consider "entitlements".
It's all the same debate, really. After all is said and done, rights function to entitle you to things or acts. The blurry line that I believe you might be talking about has a very specific name, but recent social and public discourse make a lot of people nowadays automatically cringe at it's sight (wrongly, IMO) without seriously hearing out or considering it's merits. I'm talking about the word "privilege".
