For What Reasons Should Pierre Poilievre Not Be The Next Prime Minister?

I know the Liberals have yet to announce who they will be running so maybe it's not fair to ask this question until then, but I want to hear the best argument to why you shouldn't vote for Pierre this election.

Personally I'm not sure if cutting the carbon tax will provide any good to the average Canadian or just benefit large corporations, and I don't like his support of crypto currency.

Still this isn't anything extremely persuasive.
