I saw a cop wearing a Blue Lives Matter wristband. Should I be offended?

If the math is unclear:

Time + Action = results

Not

Action = results

As in “I just explained this thing to the guy again, he should immediately agree with me, as I have now utterly and irrevocably changed his mind on this matter.”

Seriously. When was the last time you actually saw someone change their mind? It doesn’t work like that. At all. Minds do change, but you’ll never see it happen. If that’s discouraging to you, perhaps activism isn’t your field.
