he's actually right
the main reason incest is repulsive to us is because it is not evolutionarily beneficial considering the amount of defects and diseases children born from incest have
if incest didn't produce such evolutionarily bad results, then there would be no logical reason to bar two consenting adults who happen to be siblings from engaging in sexual behavior
start using your minds and maybe you'll understand why you think they way you do
I may not be using my mind... so be cautious.
But evolution isn't solely about physically good results or evolutionary bad results from birth.
There is a reason men look the way they do and women think, behave, and rationalize the way they do. There are certain traits and behaviors that are most beneficial to social animals.
Considering human being are social animals, I would say these atheist are perverted fukks. There are "logical reasons to bar" two consenting adults who happen to be siblings from causing each others juices to flow. First off, your social instincts and sympathies naturally are drawn toward people of ur same community and culture... this is why we are successful. Community and Families is what evolution and human common sense has told us is most effective in keeping our species progressive. There are current liberal progressive ideas about these things that are biological and socially regressive.. but we attach labels of 'new age, and 'progressive' to them, so it verbally brainwashes us to go a way from the moral virtues that has made us successful. I seriously though u guys worshiped Darwin?.. he preached some of this shyt.
NTM it isn't all about birth defects retards. A limited gene pool is something that every organism on earth stays away from if they can help it. Our brains and bodies have changed so much in the last 20K years... and that's because most men aren't fukking their mothers or sisters - U sick fukks.
Also, If you're atheist you should be the main people saying the opposite of what these perverts are stating. If one can conclude that religion was just a perfect way to help men rationalize with the world and deal with his own mortality... then one can make parallel assumptions about why we've Globally developed sexual rules and customs that tell us that sex with siblings is wrong.
adam and eve's children didn't have sex with one another.. humans were around way before that, btw.
