Well, besides the fact that I have also felt the Spirit drawing me to that conclusion as well, it continues as logical:

1) God will not burden us beyond what we can bear.
2) God has replied "No" to both the request to become straight and to be given the strength to be celibate.
3) Scripture does not condemn homosexual behavior per se.
-----------------------------------------------------------------------
4) There must be an acceptable way for homosexuals to behave outside of heterosexual marriage or celibacy. (Gay marriage seems a likely candidate.)
-----------------------------------------------------------------------
5) Homosexual sex under some set of conditions is not sinful.
