This is one of the many reasons you can't elect Conservatives and pretend you care about LGBTQ+ or any other marginalized group.
Conservatives want to restore or otherwise conserve traditional hierarchies. That's it, that's what it comes down to. So it doesn't matter what they campaign on, or whether they've gone after a group "lately", if you aren't a member of one of the traditional hierarchies you will eventually find yourself a target. Just look at the US, how long did it take for Conservatives there to finally win on abortion, on money being speech, on rolling back voting rights? Don't think for a second that isn't the plan here, that it won't happen here, it's already happening in some provinces and mark my word Pierre is keen to take this stuff national.
So if you want to know who's next, just reflect on the traditional hierarchies. Rich over poor, white over PoC, God over man, man over women and children, self over society, straight over LGB, and cis over trans. I'm sure I've forgotten a few, but Conservatives won't forget.
