Lumping
We hate to be lumped. Especially with people worse than us or more extreme so we’re always differentiating between why we’re different than them. As we probably should. Since we know we hate being lumped we often use the tactic to attack others and lump them in so that they can hate the lumping.
This is why knowing is so important. We can’t lump something we don’t know with something we do - just because it’s convenient. We have to take the time to see if the lump is accurate. And we have to know ourselves enough to know that when we’re lumped, someone saw enough of a connection to merge us. It might be worth looking at what that kernel of reality was.
In short, lump less. Know more, including when lumped, the why.
