"You can apologize, but you can never take back your words."

Former prime minister Steven Harper made a formal apology to Indigenous people abused in the residential school system.

Member of Parliament, Pierre Poilievre commented on the apology, "Some of us are starting to ask, are we really getting value for this money (compensation to victims), and is more money really going to solve the problem? My view is that we need to engender the values of hard work and independence and self-reliance."

Harper was furious with Poilievre who apologized the next day but the damage and hurt had been done. "You can apologize, but you can never take back your words."

“Better to trip with the feet than with the tongue.” Chances are you heard this wise advice from your Mom when she reminded you that if you can’t say something nice, don’t say anything at all. Turns out the ancients and Mom were onto something. No matter how you might wish you could take back hurtful words or scathing criticisms hurled. Words have power.”

The above was in 2008 and it appears Mr. Poilievre hasn't changed his tactics or rhetoric.
