If what you say is true, then why this....

“Vice President Biden and Nancy Pelosi should certainly not receive Communion, either at the papal installation or anywhere else,” said the Rev. Frank Pavone, founder of Priests for Life, a U.S.-based Catholic anti-abortion organization.

If they shouldn't receive it - THEN DON'T GIVE IT TO THEM.

[Louis Foxwell]

Communion is an anonymous act, between the penitent and God. The priest, as intermediary, treats each individual with complete anonymity. It is not his role to turn anyone away from the communion table. It is the responsibility of the penitent to accept the body of Christ with a clear conscience.
The rationale of lapsed political Christians who claim, falsely, that their political responsibilities are separate and distinct from their religious obligations are in mortal danger of damnation.
