There are so many people with hereditary genetic disorders that we allow to reproduce. We also allow people to reproduce that have absolutely no means to even take care of a *****. My main point is it shouldn't be a criminal offense when two adults want to have sex. Also abstinence is not the only way to 100% ensure there won't be any *****ren. Option 1 birth control, option 2 condoms, option 3 morning after pill, if all else fails option 4 abortion.
The methods you point out are, as I said, not foolproof. Pills, condoms, the 'loop', they can - and eventually will - fail. Statistics, happens all the time. And as I said, as long as there are more than one person involved, you cannot be sure what the other wants and does.
Plus:A relationship breaks up, in so many cases. You walk away, and just try to blend that person out.
How do you do that when your former lover is ******? What do the others do, ******, father, did you think about them?
****** is about SO much more than just sex
