Virtue signalling to me is someone saying 'Look at me! I am being kind!
Examples abound on FB, the my son has said he wants to give some of his toys to poor children, what is the best way for him to do it? well, maybe just take them to a charity shop or email the toy library........but then again you wouldn't get all the what a lovely child you have raised, hun comments.
Oh, and we have a local man who lives mainly on the streets (by choice), is known and looked after by all, but there is always someone who has to announce that they saw him today and bought him a sandwich..... yes we know.
Oh, and what about I have cooked too much food for Sunday lunch, where do the homeless hang out so I can take them a plate of dinner?
Now, that is virtue signalling, seeking out approval
