Exile,
I completely agree. I would make the case that the Pope could not appoint a female cardinal because it is outside his authority to do so. Similar argument as the one against girl altar boys, really. Except in this case the position of cardinal is girl altar boy x 1,000. 2,000 year Tradition of NOT ONLY male cardinals, but clerics as cardinals. The libs spout off about "lay cardinals", but these occassional lay cardinals were not laymen. They had received minor orders and were thus clerics. Most were bishops and priests. That this office was tied to orders is undeniable! The entire Tradition of the Church testifies to it. Canon Law of 1917 limited the office to priests and bishops. The '83 code that these Neo-Caths worship, limited it further to bishops only! Both of these decisions were in line with Tradition. They tied the office more perfectly to Holy Orders.
These complete and utter legalists say that if a practice was not specifically prohibited by name in the past, it is therefore allowable. This is complete BS and they know it. As you said, the idea of female cardinals was completely absurd to anyone who lived in the 1965 years previous to the "New Springtime." Why ban something by law, that nobody is seriously even challenging or proposing.
With girl altar boys, the practice was not only prohibited, but condemned as evil by three Popes! It was prohibited even by Paul VI and JPII! And they STILL said the Pope could do it if he wanted to. So they jettisoned 1990+ years of Tradition and allowed it. In my opinion, that decision is completely illicit and non-binding. The Pope does not have authority to jettison 2,000 years of Church Tradition, practices, rites, offices, etc. based on his personal whim. He is not an almighty dictator. If the Pope decreed that every Catholic must wear clown shoes to Mass, these imbeciles would go shopping for them. It really is past creepy and bordering on idolatry/ cult territory. Obedience is truly their god.
