Biological Illogical?

Tom Goodman:

In an opinion piece for the LA Times, Dean Hamer and Michael Rosbash say that, since homosexuality is based in biology, “fundamental rights” naturally follow, including, they say, gay marriage.

Is this the logical inference, though? The same field of study unearthing a biological basis for homosexuality is exposing a biological basis for things like alcoholism and aggressive behavior. Simply identifying the biological contributions to our impulses and attractions doesn’t really settle the question of the rightness of acting on our impulses and attractions
