Yes? Democracy is essentially exactly that - tyranny of the majority. The reason why successful democracies have so many checks and balances, constitutions that uphold essential rights etc is because of this fact. Really the main benefit of democracy is that it prevents the government from doing things which are wildly unpopular. To the extent that it "gives the people power", that is neutered as much as possible to prevent the majority from going "hey, we don't want these people here" and committing democratic genocide or whatever.
