No, you did demonstrate it to be anything other than remote cooperation with evil in the text you quoted. It said nothing about voting and is not intimately connected with the evil act. You need to expand on that if you are making an argument that it is more than remote cooperation with evil.
If you claim that the bishops or the Pope says otherwise, please provide the full text.
I see. No matter what is cited, you will just deny that it means what it says.
There is a proportionately serious reason to justify tolerating the evil of another.
You keep ignoring the crucial thing. Voting for abortion is morally tolerable only when there is a proportionate reason to do it. Both Pope Benedict and the above citation say that. Again:
Sin is a personal act. Moreover, we have a responsibility for the sins committed by others when we cooperate in them:
by participating directly and voluntarily in them;
by ordering, advising, praising, or approving them;
by not disclosing or not hindering them when we have an obligation to do so;
by protecting evil-doers
Formal cooperation refers to agreement in the will regarding the evil act. We may never assist another person in an external sinful act, and intend its sinfulness. Such formal cooperation is always sinful, a sin against charity (scandal), as well as of the same kind as the act in which one cooperates. For example, to willingly drive someone to get an abortion, to pay for it, encourage it (if it determines their will to do it), defend the doing of it etc. is gravely sinful, both against charity and against life.
Any direct close cooperation in the sinful act of another, while claiming not to embrace the evil intention, is tantamount to formal cooperation. For example, lending the money for an abortion out of a motive of friendship, is inseparable from the allow abortion.
Cooperation in the sinful act of another by material support which is remote, that is, not intimately connected to the evil act is sinful. However, under certain conditions it can be tolerated.
“The act by which cooperation is rendered is not itself sinful; that is, it has two effects; the good one is chosen, the bad one is tolerated.
There is a proportionately serious reason to justify tolerating the evil of another.
The danger of scandal is avoided, by protest, explanation, or some other means”
Now, what’s your reason that’s truly proportionate to the murder of a million children per year?
