Wrong. Carefully remove pink blinkers before reading... gay people don't have opposite gender partners, and straight people don't have same sex partners. Horror! Culd ir be the diversity of lifestyles 'other then that' are identical, yes, but overall its still a lifestyle.
Some homosexuals have far more in common with heterosexual with similar lifestyles than they have in common with other homosexuals. "lifestyle" broadly referes to attitudes, pastimes and values, the gender of the partner just being a small consideration among a multitude of other attitudes and values. I don't see the point in trying to compartmentalize homosexuals based off of this as though it must be a substantial difference.
