Do you understand the concept of “incidence” of occurrence? Male homosexuals are perhaps 2-3% of the total population. Figure it out. Yes, pederasty is a part of the “gay” lifestyle. Have you heard of Nambla? The only international organization devoted to the sodomization of children on the planet.
NAMBLA is a drop in the bucket compared the size of commercial child prostitution and pornography operations around the world. NAMBLA publically positions itself as a political activist group, and has managed to convince you it’s got significant numbers and clout, but it’s really a very small outfit that’s very unwelcome in most of the gay/lesbian/etc community. Reliable statistics are hard to come by, and though they strongly suggest that a significantly higher percentage of all homosexual adult males, than of all heterosexual adult males, abuse children, your claim that “90% of homosexual men” sexually abuse boys is totally off the wall and unsupported by any evidence at all.
