It's not a question of whether we should fight this (or any issue), it's a question of where and when.

Let's use Max and supply management as a case study, because it's a great example of someone losing on an issue because they chose poorly where and when to have that battle.

Max campaigned against supply management in the 2017 CPC leadership race. His stance on supply management is largely believed to be the the factor that just barely cost him the election, because the dairy lobby all voted as a bloc and as a result, Scheer won by a hair.

Now, if Bernier had just understood the electorate, shut the fuck about supply management in 2017, get elected leader and then hypothetically won the next federal election, he could have just ended supply management with the stroke of a pen. No problem.

But because he chose the leadership election campaign as the time and place to fight this supply management debate, he lost and will never get his way on that issue.

Same goes any issue. If publicly arguing your stance on gender ideology, or climate change or whatever and making a campaign issue out it is guaranteed to result in you losing, then you don't do it. You STFU and pick your battles, then if/when you win the election and take office, that's when you can turn your beliefs into policy.
