Your argument doesn't hold water, as usual. A particular species, to be applicable shouldnt we see this type of behavior among certain lions, among some tigers and elephants as we are to believe that some humans are heterosexual and some are homosexual? To point out one species and say here we have homosexual behavior within this specific species is not justification what it probably is our own observation is either outright wrong like you are Replacement AGAIN or tainted by some other outside motivation.
