In actual democratic systems, the stronger great majority (eg the 75% or 90%) can do anything they want to with a weak minority. There are many prominent examples of democratic systems being used to implement might makes right via majority abuse of the minority.
You have to intentionally neuter democratic systems with strict constitutions that protect individual rights, to prevent might makes right from always taking over democratic systems. You have to put very strong constraints in place to prevent the stronger majority from harming the weaker minority; you have to put the democratic majority in a straight-jacket that limits their possible actions for the protection of the minority.
