Consider just this single fact about semen: it is an immunosuppressive.
The fact that semen is immunosuppressive has been known for decades. Search for "semen + immunosuppressive" and PubMed Central will come up with more than 240 results.
The reason semen is immunosuppressive is obvious: if it weren't, there wouldn't be any babies.
The body recognizes everything which enteres as either self or non-self. Every human body recognizes entering semen as non-self. The immune system attacks and eliminates semen as soon as it enters ... or it would if semen did not carry a lot of agents that suppress the immune reactions of the receiving body.
As early as 1977 Lord, Sensabaugh, and Stites wrote in their paper Immunosuppressive Activity of Human Seminal Plasma:
In 1995 Kelly published a paper on his own: Contraception: Immunosuppressive mechanisms in semen: implications for contraception. In this paper he said:
As indicated elsewhere, homosexuality is an addictive disorder with a lot of negative sequelae. Pretending that Muslim shooters are the greatest threat to homosexuals is simply denial of the obvious reality: homosexuals are a greater danger to themselves than anyone else could be to them.
I predicted this on a Facebook post a few hours ago, but didn't expect to get confirmation so quickly. It looks like the Orlando shooter, Omar Mateen, was a regular at the homosexual bar, Pulse, and had a profile on a homosexual dating app. In fact, reliable reports indicate he was homosexual.Why is this not a surprise?
Rates of interpersonal violence are much higher within the homosexual community than they are in normal communities. Straight people don't beat up homosexuals. Homosexuals beat up homosexuals. They always have. No one talks about it, and attempts to deny it are legion but the facts are clear: homosexuals make up 1-2% of the population, but 43% of America's mass murderers.
