Well, the headline is dishonest at a minimum. What "some Catholics believe" may or may not have anything to do with the Catholic faith. Dietary preferences have nothing to do with the faith, that's a personal matter.
It's interesting that the headline does not refer to the beliefs of "some Unitarians" or "all Buddhists".
As a Catholic nun whose book was made the movie Brides of Christ said in her life story,
"the Pope should not interfere in matters of individual
conscience."
Right now, Catholic taxes are stolen and given for
Lockheed planes and Lockheed bunker buster bombs which are burning
the little ones of Lebanon. Prolife is universal..
no war, no executions, no slaughterhouses.
Isaiah: I delight not in yoru blood sacrifice.
What you call 'godless leftist ideology' is the socialism
of Jesus and His true followers who held their possessions
in common.
