virtue signaling

The visible expression of moral values, like wearing your emotion's on your sleeve.

It's also when someone publicly expresses opinions to demonstrate one's moral correctness on a particular issue. For example, "Canadian critics say Trudeau is more interested in "virtue signaling"—using photo ops and tweets to make himself look noble—than in effective policy."
