The league has its own issues.
It is not the official voice of the Catholic Church.
So, I’ll take what they say with a grain of salt.
If the mayor wants to tweet on any topic, so be it…it hardly constitutes “abuse of office”, what it does constitute is personal opinion…if voters (and not just the Catholic League) are upset they have every right to take those feelings into the voting booth.
The mayor, is under no obligation to uphold church teachings as an elected official. He does not answer to the Church in those matters.
If he is a Catholic, then there are ecclesiastic legal issues for him to deal with in defying the teachings of the Church, but those issues, while we as Catholics may consider to be serious enough to put his soul in jeopardy, his views are not an abuse of power.
The Catholic League needs to get over itself.
