The problem I see is you can end up with a tyranny of the minority, which in a sense leads to a revolt of the majority, and minority rights become restricted again.

"To protect minorities implies restrictions on the rights of the majority"

I would submit that this is a sweeping generality, and not necessarily applicable to most basic rights (I do concede that there is a rather broad definition of the term basic rights :D and my contention can easily be dismissed with a few specific examples)
