Don’t hold strong opinions lightly
I often hear people claim to have “strong opinions, loosely held,” as if it’s a good thing. But this is actually a toxic stance that undermines exactly what the speaker is trying to imply. — When people use the phrase they want to imply they are decisive but not headstrong to the point of being unreasonable. That they’re willing to change their mind when presented with enough counter-evidence. Which sounds reasonable. But it’s actually an idiotic stance.
