I can't say that I do either but I won't dismiss it completely.
IMO, It's a concept meant for the collective action of nations that can act and who feel compelled by their values to act. Not the responsibility of just one nation no matter how powerful/wealthy compared to others and not without the consent of the governed who will be required to serve and sacrifice for others with no definite end in sight and no assurance of success.
All of those caveats have not been met by those advocating for humanitarian intervention. No honesty as to the cost, the time and risks.
Powers and those who push for western nations, especially America, to act on the concept of the Responsibility to Protect along with those who push for what I would call Indefinite Engagement aren't honest about what it required to execute missions that act on these ideas and that dishonesty erodes trust in leadership, exhausts a military structured to mainly deter and win conventional conflicts and breeds a cynicism in the public that infects every other way we view our government.
Joe Kent wrote a good article on this at Breitbart:

From the article:
If the American people do want to go to war for human rights, then we need to reinstate the draft and double the size of the military. There are plenty of places in Africa, the Middle East, and central Asia that we would need to fight decades-long conflicts in to right the world’s wrongs.
That is probably a pretty good overview for what would be needed along with financially capable Allies being required to do the same and participating in these missions with no ROE restrictions, not holding breath for that. Likely, whole conventional mission sets would need to be dropped to shift resources to grow other mission sets to handle this much demand for Occupation/Stabilization forces.
I'm not for America alone to go out and fix the world but if the Western world just can't tolerate the mass tragedies then we have to be honest as to the cost, risks and requirements while explaining clearly to the people who will bear this cost as to why and what are they sacrificing for.
