Agreed, Jesus did come to save us sinners. However, our Lord clearly indicated that eventually...if someone who claims to be a brother (or sister) is intransigent, and won't be corrected privately or publicly, than they must be thrown out of the Church...and this must be public.
Pelosi and other politicians like her--who base their careers on being pro-abortion AND Roman Catholic fit this description perfectly.
"If your brother sins against you, go and show him his fault, just between the two of you. If he listens to you, you have won your brother over. But if he will not listen, take one or two others along, so that 'every matter may be established by the testimony of two or three witnesses.'If he refuses to listen to them, tell it to the church; and if he refuses to listen even to the church, treat him as you would a pagan or a tax collector." (Matt. 18:15-17)
Oddly enough this passage is immediately followed by one commonly attributed to establish Roman Catholic authority: "I tell you the truth, whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven."
What good is a Church's authority if never exercised?
As a side benefit of the public excommunication of public officials, it makes it clear to the faithful that what the public officials are doing or supporting is wrong.
Thou shalt not kill is one of them.
