just be honest, you don't like GPL. The reason you don't like GPL is not because it's not enforceable, but because you don't want to enforce it, or be subject to its strictures. Your argument that you use MIT because GPL is unenforceable makes no sense, as I pointed out.
(also, it is enforceable and has been enforced, but that's a separate topic.)
