Disagrees is one thing. This guy sounds like a rabid attack dog.
So? He is not running for anything. If you agree on politics then what does it matter. As long as you stay free to defend your faith, as long as Hagee’s beliefs are not imposed on you by law, what does it matter? I vote for Catholics all the time and I’m not Catholic. The guy is a pastor. He will be vocal about his beliefs. Or at least I would hope so. It’s not like Catholic priests and bishops and theologians want to be stiffled in expressing their theological disagreements for the sake of political unity. No one should have to sacrifice one for the other. If we agree on moral principles and political structure of government then we should be happy. Let the divisions of religion and theology remain and be debated/defended. That’s the only way religious freedom survives.
