Not sure this should be in Canadian politics since virtue signalling seems universal. But certainly Trudeau proudly calling himself a feminist at every possible opportunity, and insisting half his cabinet would be female is virtue signalling. His insistence on taking all those Syrian refugees immediately following the news viewing of that dead boy on the beach was virtue signalling. Him putting 'middle class' into every speech about fifty times is virtue signalling. Marching in gay pride parades when you're not gay is virtue signalling. Even his 'town hall' things are virtue signalling (look at me, I'm a honest, ordinary guy who likes to talk to you ordinary folks!).
Down south, it's all virtue signalling. The NFL kneel downs for the national anthem are all about virtue signalling - on both sides. You think Trump even knows anything about football or has ever watched a game? You think the owners holding arms with Black football players who won't stand up is anything but virtue signalling when what they'd really like to do is fire their asses? Politicians who waves guns on stage to show what rebels they are, that's virtue signalling, as is every political ad carefully crafted to have multicultural people in it.
Coke has new TV ads featuring gay and transgendered people in it. Pure virtue signalling.
