But that's not what ignorance is. Spicer knew that the crowd was small and he called it large. That's a case of him lying, not a case of him being ignorant.
It is ignorant to demand clear falsehood is truth.
It accomplishes nothing except making one look stupid and tyrannical.
No, ignorance means thinking that those falsehoods are truths because you haven't taken the time to fact check. Fact checking them, realizing that they're false and then asserting them as truth anyways is a lie.
These people are liars. Stop trying to apologize for them by categorizing them as simply ignorant.
Now, Trump himself may very well be ignorant. Spicer and the rest of the Trump apologists know that what they're saying is a lie and they say it anyways.
