Its far fetched but doesn't mean it is "crazy" Come on how can two guys together be natural? putting it in the poop shoot is natural? or let alone two women scissoring? vaccines are they natural? No they are man made.. Really thats how it was meant to be? .. Man and woman are a fit because they can reproduce keep the population growing. I am not denying that the same sex cant love each other, father n son, brother n brother, but its not homosexuality that is a disease, its sex... Sex is a problem, it can be an addiction, cause people to do some crazy things, rape for instance(not saying all rapist are sex addicts), sex is out of control in todays world, it went from private between two people to world news headlines..
All I'm saying if humanity was on the brink of extinction you wouldn't want the last few guys alive to be gay, and vice versa. Even if they could get it to work it wouldn't be very successful. It aint natural, and It could be very much possible that vaccines could be the cause..
not saying it is, just saying anything is possible.
