Abortion: should only be used to protect the child from defects, disease, etc.
Death Penalty: it's the easy way out for the criminal. The family and friends of a murder victim have to live with their loss for the rest of their lives. Why should the criminal's suffering be put to an end? And if we must kill them why do we do it in much the same way that a sick animal is put down?
Evolution: the way of the world
Cloning: so many of today's diseases could be cured with the help of stem cells but our antiquated beliefs won't allow that to happen
Sex before marriage: again, antiquated beliefs. These two things aren't mutually exclusive
Is it ok for a person to cheat under any circumstances?

eople have done it for centuries and we're still here
Homosexuality: it's also been around a very long time
Antisemitism: one of the main reasons I'm not religious. It boggles the mind to think that we still treat people differently because of what they believe
I'm throwing another one in: global warming. I think it's blown way out of proportion and it gives people a way to feel good about themselves for doing something good for the environment. A natural climate change doesn't make for good news stories but humans destroying the planet with our cars and factories sure does.
