No offense, but an unsupported, “I found an online web site that claims it is prolife and engaged in a lie to try to ‘trick’ abortion agencies” means what?
A. There is no proof that the poster actually saw any such web site. (no offense to the OP, but anybody can ‘say’ anything, and that doesn’t necessarily mean what they say happened.)
B. Anybody can ‘make’ a web site and make any claim they choose. Doesn’t mean that the claim is truthful or ever happened.
C. Anybody can claim to be an ‘advocate’, and they can even make dubious or immoral choices as an individual, but that doesn’t mean that the group they claim to advocate for does those immoral things OR that it would sanction such things.
Now when I see American Life League, the USCCB and the Vatican all come out and say, “We charge and adjure all Catholics on pain of mortal sin to lie to abortion facilities in an attempt to make them look like racists so that it might convince people to shut the facilities down for racism since they won’t shut them down otherwise”. . . then I’ll believe that this is ‘authentic’ prolife teaching. . .
And I’ll also become Jewish, because if the above ever happens it would mean that Christianity itself was a fraud. For if the Church would thus ‘change’ its teaching (which has been that ‘one may never do evil even if by doing so a ‘good’ may result’), then it isn’t really what it claims to be. And since I do believe in God. . .if Christianity were to be shown as false, the faith that would remain would be Judaism.
