Be honest about these three conscience-raising values, NOT politically motivated based on ideology or agenda.
Abortion: It's a life, not a choice. In 100 years, people will look back on the pro-choice crowd as people look at at the pro-slavery folks of the 19th century today. History will not be kind to the pro-choicers. And the US government will be chastised for making in-country adoptions so expensive and difficult that people had to adopt out of the country.
Racial bigotry: Governments and some political parties use this to control the way some vote. These people must be stopped. Affirmative Action, for example, is nothing more than State-sanctioned racism. Anyone supporting this is a racist by definition.
Gays: Homosexuals should be treated just like everyone else. However, many have become homosexuals because of physical and/or sexual abuse as children and some perhaps because of a chemical imbalance in the brain. The answer is not to encourage the behavior for these people, but to help them become who they would have become had they not been dealt the hand they were given. Just as there is treatment for bipolar disorder, for example, there are treatments available for homosexuals today and more sophisticated treatments will be available in the future.
Christianity: Humans are wired-up to believe in God. Christianity seems to have it right, although the fundamentalists have clearly corrupted the meaning. If people would follow the two greatest commandments, the world would be a better place:
Mark chapter 12 verses 28-31
One of the teachers of the law came and heard them debating. Noticing that Jesus had given them a good answer, he asked him "Of all the commandments, which is the most important?"
"The most important one," Jesus answered, "is this: Hear, O Israel, the Lord our God, the Lord is one. Love the Lord your God with all your heart, with all your soul and with all your mind and with all your strength. The second is this: Love your neighbour as yourself. There is no commandment greater than these."
One last thing: I find it disgusting that the meaning of 'Liberal' has been corrupted by contemporary American liberals. I can't call myself a 'Liberal' without explaining that I'm not like the left-wing moonbats. The current meaning of 'Liberal' in America today is just about the opposite of the dictionary definition. That's a shame.
