Homophilia and obesity are sort of an apt comparison, though.              We can't use homophilia as a catch-all phrase, esp. not in the same context with obesity.      Numerous researches prove that male homosexuality is on the polar opposite end of the spectrum from female homosexuality (esp. in the case of  'politican lesbians') in terms of obesity  - with heterosexuality being somewhere along the median.       But it really is just a confirmation that social stereotypes aren't born without a good reason.
