If you want to have an argument, to raise tempers or to distract, the easiest thing to do is start bringing up things that are easy to argue about.
Not the things that are important.
Because the important things require nuance, patience and understanding. They require an understanding of goals, of the way the world works and our mutual respect.
If someone keeps coming back to an irrelevant, urgent or provocative point instead, they’re signaling that they’d rather not talk about the important thing.
Which is precisely what we need to talk about.
