The Tebow character and his sponsor both look like so many others of their ilk that talk big about sexual sins, and who (one day) are discovered to be doing precisely what they condemn so zealously. This could be a result of their internalised fear of their own personal inclination to homosexuality. So it may be that the stronger the attraction of these men to other males (and its mainly men that become so vociferous about men having sex with men), the more they condemn it in public, as part of a never-ending struggle against their own lust. It often becomes hypocritical when the public talk masks their secret sexual escapades with other men, witness the many examples in American public life.
Examples of this can often be seen in American public life. (probably the same in other nations also, but the American example is better documented) The odious McCarthy of the immediate post war era, conflated and demonised homosexuality with communism, and was surrounded by men who on rational examination were motivated by their own internalised homophobia. Here are some of the names of that era, who were secretly homosexual, but often loud in their denunciations of homosexuality. We could start with the most powerful (at tht time) man in the USA- J.Edgar Hoover, head of the FBI. Extremely powerful because his secret files were as good as the later East German Stasi, listing all the secret dirt on the who's who of US Society. Hoover was single all his life and lived with his 'best friend' Clyde Tolson, who was employed at FBI HQ by Hoover. It is now well-known that Hoover was same sex attracted.
Here's a pik of hoover and his gay partner relaxing together. (from Wikipedia)
Hoover made the bullets that McCarthy fired - not only against communists - but also against homosexuals.
Secondly, we could take Cardinal Francis Spellman, though I'm not quite sure that he had a strong 'internalised homophobia.' I think he really enjoyed his attraction to other males. As Archbishop of New York he also was extremely powerful (he became the richest Catholic prelate in the US Church). He is described as having a succession of boyfriends and holding discreet gay parties. Also a close friend and supporter of McCarthy, and a purposeful ally in the McCarthy witchhunts, he arranged an adoption for the McCarthy's when their marriage proved childless.
Another key figure was a psychiatrist, Harry Stack Sullivan who also lived with his male lover. Sullivan can surely be indicted as hypocritical and with an internalised homophobia. During WW2 he designed screening tests to weed out homosexuals in the military. Not sure how successful the tests were, that's something I'd like to research one day. I suggest that Sullivan worked with McCarthy to expose possible homosexuals in government.
And, then there is the infamous Roy Cohn, McCarthy's right hand man, a N.Y.Lawyer and McCarthy's fixer. Curious is it not, that Cohn' efforts led to McCarthy's downfall when Cohn tried to arrange special privileges in the US Army, for a David Schnide with whom he was infatuated. Cohn was the ultimate homophobic hypocrite. Nicholas von Hoffman, wrote a biography of Cohn, called Citizen Cohn. One of Cohn's former staffers described how he would drive Cohn to functions held by 'family first' type groups where Cohn would make vicious attacks on homosexuals (enemies of the state stuff, maybe???) On these occasions Cohn would be accompanied by his current boyfriend, and they would then go off to dinner together.
With so many 'friends of Dorothy' around him, it's easy to start wondering about McCarthy himself.
Internalised homophobia is well discussed in the academic circles concerned with emotional and mental health (although, there is discussion as to whether 'homophobia' is the best term).
It is clear that in western, Christian society with the terrible inner (emotional) tensions created by the doctrine that the 'spirit is against the flesh' (Galatians Ch 5), not just for the same sex attracted, but for heterosexuals also, it is little wonder that people finish up 'awkward' about sex. For those who are 'gay,' as we now describe this age-old phenonemon, the problem is exacerbated by past social condemnation. Since humans are social animals, this is a difficult problem. Little wonder that some same-sex attracted people become 'homophobic.'
