Sorry not Christian, born into a SIKH family but according to our scriptures we are allowed to have open minds and approach any religion with an open mind. So me I'm non religious but feel certain religions all have good points. Now back to the topic although in SIKHISM it states marriage is not subjective to our human form but rather it's the connection of our souls. So sex, creed, race, colour all do not matter it's whether the love is pure. Also regarding LGBT's it states that humans are all free and equal and have the right to do as they feel. But anyways besides all that I still feel it is very wrong to change your sex, personal opinion I guess.
