I watched it also and have the same impression as you. When Biden said he is “prepared” to accept the church’s teachings on conception, it was just cold, meaningless political positioning. Pelosi and Biden have created a disaster for themselves, assuming that the church will bow to their heresy simply because they’re powerful politicians.
These liberals who preach incessantly about separating church from state have show that they really have no soul. It’s all about political gamesmanship and they are making a disastrous mistake imposing themselves in the church’s domain on something so vital as the protection of human life. It’s their votes that count, not their “beliefs” and all their incessant crap about not imposing their beliefs on everyone else, blah, blah, blah. Everytime they display their hubris in such a despicable way they lose more and more Catholic support.
