Dude, you just oversimplified like a whole paragraphs of explication into a couple of short simple sentences...-_-
You read the first sentence and ignored everything else. My not having a girlfriend is because I am 18. I am not bleeding from loneliness. It is not very unusual for people my age to not have a girlfriend. Plus, to be honest I live in a pretty bad neighborhood so my options are not stellar. You make it sound as if though everyone here that agrees has very sad unfulfilled lives. Also, I heavily implied that it is out of love that I agree with incest. Sexual desire is not the factor for me agreeing with love among siblings. It is simply a more than acceptable byproduct.
To call the vague and biased statement a theory is honestly an insult to science. You have no proof or rational to back it up. I backed up my counterargument with logic. If we ask the people here I am sure that more than one that will say they have a girlfriend and agree with incest out of the roughly 20 people that have posted here not all of which agree with incest. That margin of error is large to call your statement a theory.
