Exactly, politicians can actually cause the deaths by their votes, this guy can only express his opinions. I am glad they finally got this guy out, and you are right that the church is FINALLY stepping up.
The priest who strays is in fact far more harmful than the politician. He may cause many, many more deaths by giving cover to hundreds of death-minded politicians, not to mention putting immortal souls at risk. Plus, of course, he's betraying his vows of obedience.
