That's just the decorum/civility myth that people have convinced themselves has to apply to conservatives, largely at the urging of progressives. If any of them are rude, they're not fit to govern, blah, blah, blah. Ideologues blowing out their gaffs with public spending and canceling expensive projects they disagree with are much greater problems for BC and Canada than a handful of past comments from people whose names no-one will recognize in six months.
Most of the nonsense comes from people who will never be more than backbenchers in the highest tier of seats at the back. Actual governance comes from the leader's office and cabinet ministers. It's not hard to find enough people to fill those slots. Every party out of government for a while faces a learning curve that is fixed only by governing.
