I hope someone has mentioned somewhere in the discussion that the x chromosome in males comes from the mother.

Therefore all of the shared traits (increased fecundity, homosexuality, etc.) follow the pattern of gene on an inherited x chromosome.

The female chromosome carrying traits associated with sexuality does not seem like a big intellectual leap of faith, but rather seems pretty plausible.

Homophobia is going to have the same linkage, btw.
