Homosexuals Molest Children At A Far Higher Rate Than Heterosexuals
Homosexuals account for only 1-2% of our population based on current surveys. The National Opinion Research Center in 1992 found that 2.8% of men and 1.4% of women identified themselves as “homosexual” or “bisexual. A 1995 survey of 18-49-year-old men published by the Journal of Sex Research indicated that 2.6% of them had engaged in homosexual sex within the prior 12 months; 4% had had homosexual sex within the past five years. In other words, at least 98-99% of our population is heterosexual in orientation.
Homosexual activists routinely claim that most child molesters are “heterosexual” males, thus shifting the focus away from their own very high rates of molestation. Since 98-99% of the population is heterosexual, it is technically correct to say that most molestations are done by heterosexuals. However, statistics indicate that homosexuals pose a far more serious threat to children than do heterosexuals.
For example: In 1987, Dr. Stephen Rubin of Whitman College conducted a ten-state study of sex abuse cases involving school teachers. He studied 199 cases. Of those, 122 male teachers had molested girls, while 14 female teachers had molested boys. He also discovered that 59 homosexual male teachers had molested boys and four female homosexual teachers had molested girls. In other words, 32 percent of those child molestation cases involved homosexuals. Nearly a third of these cases come from only 1-2% of the population.
Dr. Judith Reisman, in her book, Kinsey, Crimes & Consequences, describes the research done by Dr. Gene Abel. This researcher compared the molestation rates of self-confessed homosexual and heterosexual child molesters. In a sample of 153 homosexual molesters, they confessed to a total of 22,981 molestations.
This is equivalent to 150 children per molester. Self-admitted heterosexual molesters admitted to 4,435 molestations. This comes to 19.8 victims per molester. Dr. Abel concluded that homosexuals “sexually molest young boys at an incidence that is occurring from five times greater than the molestation of girls.”
Can you divide 150 by 20? I'm not sure how you came by the notion that I came up with the "7-times the number of victims" by myself or out of thin air, but whether you care to admit it or not, it is another statistic from the same group of studies that reached the "1-3%/20-40%" conclusions. It is a factor that MUST be included if you are going to compare the percentages of homo/heterosexuals in the general population to the percentages of homo/heterosexuals in the pedophile population.
