Frankly, most of my friends hold very different political beliefs. It's just a funny thing in this country that supposedly you can't sit down and have dinner and enjoy another person's company if you don't have the same beliefs. It's ridiculous.
Christians - whether as a priest, a nun, a minister, whatever - have just been stereotyped to death. You try to be a model of kindness and love and forgiveness to all those around you, because you have received kindness and love and forgiveness from God through Christ. That's what Christianity is.
