I'm thinking of the the same edit that I made.   No biggee, because this  FAQ sentence is a hypothetical question from somebody, not a statement, but these are my thoughts:  
"Libertarian socialism" is I think too narrow of a term to essentially describe non-US libertarianism.  You may know this better than me, but isn't there a whole lotta non-US libertarianism that is not libertarian socialism?       
"Pro-capitalism" is generally not a plank in common US libertarianism. Common US libertarians tacitly accept motherhood, apple pie, capitalism, puppies and other things, but that does not make it "pro-apple pie" type libertarianism.
