Virtue signalling
Virtue signalling is the expression or promotion of viewpoints that are especially valued within a social group, especially when this is done primarily to enhance the social standing of the speaker. For example, expressing a hatred of the right-wing newspaper Daily Mail might be an example of virtue signalling among the British left. The term is chiefly used by conservative commentators to criticize the expression of tribalistic socially progressive views on social media, but has also been used to describe analogous behaviour in other groups, such as pro-gun rights grandstanding among the American right, and by signalling theorists to discuss conspicuous piety among the religious faithful.
