This is a meaningless statement for two reasons.True, you can be a homosexual without being a pedophile. but i believe that they are sometimes co-existing situations. Despite the fact that only 3% of the population is admittedly homosexual, 1/3rd of child abusers are homosexual.
1) "...only 3% of the population is admittedly homosexual..." [emphasis mine]. There are a lot of people still in the closet about it; not surprising, given the bigotry (and sometimes outright violence) against those who don't conform to the strict heterosexual norm. Huge selection bias here; however, against a 30 Apr 2017 population of 324,956,001 (source: https://www.census.gov/popclock/ ), that's still 9,748,680 admitted homosexuals.
2) You say 1/3 of abusers are homosexual; that doesn't tell us anything about how many homosexuals are abusers. You're trying to conflate the two, to create the false impression that there are 3.25 million gay child abusers out there. It doesn't work that way. Your last statement would remain true if there were exactly three child abusers in the country, of whom one is gay. Totally meaningless statistic, presented in a way to mislead...just like the antis inventing the term "assault weapon" to confuse semiautomatic rifles with fully-automatic "assault rifles."
Of course, your own quote addresses the misleading inference you presented: "This, of course, would not indicate that androphilic males have a greater propensity to offend against children [emphasis mine]."
