How can the Referendum give a hand to the Expressed, but maybe lead to the Expressed creating a Tyranny?

-Referendums give the Expressed [Public] the Power on the Decision rather than the Implied [Politicians] and is forced for the Decision to be Respected. Happens on Devolution in 1997 -Tyranny of the Majority may happen, meaning the Majority will always get what they want, and force Minorities to be Quiet. Scots, NI and London were Forced to accept the Reality that UK was Leaving, despite them voting to Remain. England says Tough Luck.
