While this should be the predictable consequence of supporting abortion, I find the approach a bit weak.
In voting for abortion, the TD's committed a public act.
The rebuke of that public act should be public so that other Catholics know it is unacceptable to vote for abortion.
It is also a bit weak that we don't know the names of the clergy who are denying communion.
We need to know who is applying Catholic doctrine, and who isn't.
