Michael, the distinction between (1) SEXUEAL ORINETATION, be it heterosexual, bisexual, or homosexual or anywhere along that continuum, and (2) SEXUAL ACTIVITY is the cornerstone of the Church's sexual morality, and it has been unambiguously such since at least the middle ages, and probably much longer. Therefore once again, Michael, you startle me with the ancient quality of your line of argument. 

And when we through modern psychology into the mix, I am completely gobsmacked to here someone say the kinds of thinks you are saying.
