That's the rather common-sensical conclusion reached by University of Kansas professor Walter Schumm.
Should be no surprise--children imitate their role models. I can't find the citation now, but where the father is absent, it is far more likely that a boy will grow up to be an absent father, too. I even recall seeing a nature show about a mother bear with an injured front leg. The injury required her to hold her leg and paw in an unusual way when hunting for salmon in the river. Her cub watched, and when he was old enough to hunt, he held his leg and cub in the same unusual way, although there was no physical need for him to do so.
Why would engaging in homosexualist behavior be any different?
