People do raise men to be gay. Happens all the time. A few percent of parents do it (I don't know any reliable statistics). Not on purpose, sure, but parents don't raise straight kids on purpose either. (Yes, people try to "make their kid straight" occasionally, but there's no evidence the things they do actually have the intended effect.) I definitely think one day we will learn how to analyze what parents do that causes men to turn out gay, and be able to copy it (or not). However, I won't be surprised if the answer is: all present-day parents enact parenting strategies capable of causing homosexuality, but they only behave to cause it (unintentionally) when triggered in the right way (i.e., by some characteristic of young children other than homosexuality itself).
