That's... not irony.
Momentum supporters are clearly more hate filled than any other side of the political debate. That's just my own observation.
Really? The Conservatives have sailed the good ship Brexit on an anti-immigration wave that harks back to the days of the empire, where we plucked immigrants from their homelands to feather our silk lined nests. That you believe that Labour's manifesto was more bilious than this, suggests a level of myopia blinding you to reality, and the dictionary definition of irony.
