I'll throw my opinions out there as well
Abortion - I'm totally pro-choice, there are all ready many kids in this world that are not taken care of or loved the way they should be, why add more?
Death Penalty - I used to be against this, but now my feelings are an eye for an eye, I don't feel someone should be able to be so selfish to take the life of another and then get to sit in jail where food is provided and live out their life.
Evolution - all for it, believe this is how we came to be.
Cloning - all for it as well, especially if it will help cure disease
Sex before marriage - absolutely, you have to test drive the care before you buy it ; )
Is it ok for a person to cheat under any circumstances? - I don't believe so. If a person is truly unhappy there should be nothing stopping a person from leaving and finding true love.
Homosexuality - you are who you are and I would never look down on someone who is a homosexual. Infact I've had many homosexual friends and I've never felt they were any different than my straight friends.
Antisemitism - I don't feel this is right to hate someone b/c of their religion
