Which sexual "immorality" is worse?

-Consentual sex between parent and off-spring (any age)? 
-Consentual sex between siblings? 
-Consentual sex between cousins?
-Consentual sex between pre-adult/teen and pre-adult/teen? 
-Consentual sex between pre-teen and pre-teen? 
-Consentual sex between pre-adult/teen and pre-teen?
-Consentual sex between an adult (other than parent/grandparent/etc.) and pre-adult/teen? (Assume the pre-adult/teen understands sex and does consent--legality is not the issue here)
-Consentual sex between an adult (other than parent/grandparent/etc.) and a pre-teen? (Assume the pre-teen understands sex and does consent--legality is not the issue here)
-Consentual sex between an adult and an adult who are un-wed?

Again, legal ramifications are not at issue, only your own personal "morality" towards these specific pairings.

Morals are beliefs taught to children and illiterate peasants who can't come to the same conclusion through logic

Its 2006, you have the internet.  Let base decisions and opinions on reason instead of "hay thats wrong/right"
You don't support something because its "Immoral"?  what does that mean?  You don't support it because you don't like it, it makes you feel sick?  So if you didn't FEEL it was wrong then it'd be ok for you? Fascinating, but not a very solid arguement

If its not a religious arguement, cut the moral garbage

Actually its only about half or so, you just never hear about the ones that don't get traumatized

Regardless, adult+preteen is still a no-no IMO
everything else is fine
