How did the Liberals or NDP pander for BLM or "Antifa" votes?

Contrast that to Trump with his Muslim ban, campaigning on the Mexican wall, stating a Mexican judge could not be impartial.   In Canada you have the CPC promoting a "Barbaric Practices" snitch line and a niqab ban for citizenship ceremonies.    Neither policy was meant to accomplish anything except deliberately pander to the fringe element of the party.   The "Earl Cowans" of Canada, who definitely vote AND more importantly - donate.
