Part of the problem is that people feel things are true and you can't debate or logicise that away. You can't argue against a feeling because it's deeply personal and you can't invalidate feelings. The most you can offer is another perspective and hope they're willing to consider it. Short of having them convince themselves, you can't really change people's minds when they feel something is true.
