It appears as if much of the American hierarchy of your church has been coopted in the same manner as the so-called Mainline Protestant denominations.
We can vote with our feet, and just leave the deluded denominations to die. You must remain. There are advantages and disadvantages to each.
We’ll hopefully eliminate the apostacy by attrition. You’ll hopefully stand and fight.
Either way, such belief has no place in any church.
As well, the USCCB does not equal the Catholic Church.
The USCCB is actually impeding or frustrating the teaching of the Church, as explained in the Catechism and in the post at #16.
It would be foolish in the extreme for any Catholic to leave the Church over this ---though they could well consider cutting off any donations to the USCCB and re-directing them to a more worthy Catholic recipient)
Bad policies, unfaithful teachings, and disobedience to Catholic faith and morals by priests and Bishops cause scandal. Those responsible for scandal which drives people out of the Church are committing spiritual murder. But those who reject the Church because of this scandal are committing spiritual suicide.
What the Church needs is to become more Catholic. You don't strengthen the Church by abandoning it.
