What is the difference between a Facebook Page “Like” and an external URL “Like”? And will the “user_likes” permission scope give access to both?

Yes, user_likes will give you access to both.

Facebook now has two ways to read likes. If you would like to get the likes of an external URL you try this.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
