I think pro-life Catholics who support Trump and apologists for the institutional church (often the same folks) have committed the "sin of rationalizing" about FREEDOM they so often assign to others: Ends Justify Means. 

" We must always focus on the long-term greater good in our conscience-driven decision-making," say folks telling us to support Trump and the hierarchy. Imagine if a young couple said that to the bishop in defense of using contraception or a divorcing couple said that to their parish priest.
