People that publicly criticize what they secretly are.

I came across this video yesterday from Upworthy. I have always been suspicious of people who are violently discriminatory against a group of people. And now i have my proof. I am very certain that a huge percentage of homophobic pastors and politicians who think gay people should be executed are secretly gay themselves. I think its a coping mechanism of dealing with a part of themselves that they wished they could get rid of, and somehow they think if they openly disapprove and criticize it they would stop being it.
Adolf Hitler hated the Jews so much and wanted to see them wiped out of the earth. There are theories that Hitler had Jewish ancestors. Ironic is it not?
In one of my favourite books, Harry potter, Tom Marvolo Riddle (later Lord Voldermot / the Dark lord) aka he-who-must-not-be-named hated mudbloods and muggles. It turns out that he is a mudblood. As his father was a muggle(non magical being) and his mother a pure-blood witch.
My point is that people who often publicly disapprove of something are secretly that thing.
