You confuse outward appearances and self-identification with true, sincere faith.
Pelosi’s actions and statements are diametrically opposed to all true Catholic beliefs. Because she lies and says she is a Catholic does not make it so. Her receiving Holy Communion in a State of sin is in itself a mortal sin and an abomination in the eyes of God.
Many people dishonestly claim to be what they are not. Every murderer in prison says he is innocent. That does not make it so.
According to Catholicism, internal realities are inherently subjective. That's why it has water baptism instead of the mystical inward "new birth" and confession instead of someone obtaining forgiveness directly. These provide sure, certain, external, and objective surety (at least that's the theory).

It is most unfortunate that so many Catholics try to have it both ways. They slam Protestantism for its subjectivism and lack of externals, then when there are bad Catholics they fall back on that exact same internalism and subjectivity.
Priests and (especially) bishops, as successors of the apostles, I assume are supposed to have a certain degree of responsibility to see to it that externals and internals match up. That they refuse to do this is a grave scandal to even the Church's friends, much less its enemies.
If Pelosi is committing "mortal sin," then it is the duty of her bishop to provide discipline.
I was once asked to leave the Catholic Church because I interpreted the Bible "literally." Now, if I could be told I wasn't really Catholic, don't you think someone somewhere could say the same to Pelosi? Otherwise the impression I get is that "literal" interpretation of the Bible is a greater offense to Catholicism than all that Pelosi is guilty of.
