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.

>>77
say there are 10000 people in the US
6910 = American
1290 = African American
1340 = Hispanic
150 = American Indian
42 = Asian

there are 1000 cases of child abuse
out of those:

509.9 of these were commited by whites (73.8% of 69.1% = 50.9958%)
255.8 of these were commited by African Americans
149.96 of these were commited by Hispanics
19.995 of these were commited by American Indians
9.996 of these were commited by Asians

so no, blacks are not 2.63 times more like to commit child abuse than whites.
