Do you think this is genetic ?

My point was that the genetic determinism vs. learned behavior is a false dichotomy. You dont need a "gay gene" to be passed on by a gay parent to make a kid that is hard wired to be homosexual. The influence of the environment an embyo develops in on gene expression, exposure to hormores/chemicals in the womb etc. is a big factor in determining how the animal developes, and may turn out to be as big a contributing factor to the animals charicteristics as the raw genetic material.
