You're going to the same well again (because that's what rightwingers do). First you blamed criticism of the Bush Boy on Bush Derangement Syndrome, until he was ushered out of town in a well-deserved hail of jeers. Then you came to despise him so much that you denounced him and embraced the Tea Party. Now you think opposition to Trump is based on Trump Derangement Syndrome, or your fallback position of "butthurt".
Pointing out that Trump lied about his authority to end the family separation program at the border is just that. It's pointing out that he lied. It's not evidence of derangement or butthurt. Apply Occam's Razor. Suspected butthurt is extraneous. Suspected derangement is extraneous. What you're left with is, Trump lied.
