Can you advocate for doing an ethical thing like that and not have it be considered bragging? I've often wondered about how to encourage others to give more, volunteer more.

If I don't do those things (or don't claim to), people will say, "Why should I do that? You don't do that! Hypocrite."

If I do those things, people will say, "You are just bragging/virtue signaling."
