Re: the video: Who are the "you guys" you referred to? What I saw were two Evangelical Christians who claimed God caused them not to be gay and embrace their biological sex, as opposed to having a sex change. It's just another "You can pray the gay away" Christian ex-gay propaganda video really.
Indeed, that much seemed apparent from the first few minutes but I thought I'd better watch the rest of it in case I had got the wrong end of the stick. The video seems to be part of a series or regular channel and, though I haven't checked it out, I rather suspect it is all along the lines of "look what miracles can happen when your surrender yourself to God" and the gay man going straight and trans man de-transitioning back to a woman are just a modern version of the biblical miracle.
We also know that religious teaching can be surprisingly powerful. Most people have a strong sense of self preservation, yet religion can cause people to go on a suicide mission. Then the woman, at least, talked about temptation in connection with sexuality in a way that hinted she may not be completely straight. Are these a couple that are each some kind of bi and religion has been enough to persuade them each to repress their gay side and concentrate on the straight? If so, maybe this will work out for them. Or maybe things will go wrong in the future. There have been some preachers who have been very vocal about how being gay is against God's way and have then been found to be having gay sex themselves; I think I even read/saw a case where someone offering conversion therapy was caught up in that, unable to convert himself.
I don't think that video has made any difference to my opinion. It seems to me things are a bit more complicated than simple labels can adequately describe. At the moment it seems likely that we are born with a certain range of possible attraction and what we express of that may indeed change over our lives. That doesn't mean governments or the wider society should interfere in people's loves and sexual lives, other than that sex is consensual. People should not feel under pressure to repress part of themselves.
Another interesting snippet from the video: the interviewer commented how, in the past, it seemed acceptable to express a desire to kill people, but not to fancy the wrong sex whereas now the position is reversed. I am not sure if, when a person feels a desire to be violent, making it unacceptable to state the fact really achieves anything but, while violence and sex are both naturally occurring behaviors, the view I get as an outsider is that the USA has long been too encouraging about violence and too repressed about sex. If the interviewer believes things have changed, this is a good thing.
