There's no single unified group of "people in charge in the U.S.". There are various people with varying amounts of power. Some of them are religious nutters who interpret their religion as saying that anything other than traditional gender roles is satanic. Some of them are opportunists who see religious nutters as useful idiots, they rile them up over transgender issues in order to get their support for other things (i.e. tax cuts / loopholes for special interests, etc.). Some of them are somewhat liberal, but are still uncomfortable with transgender people and see their political opponents using transgender issues to rile up their base while they do really destructive things (tax cuts / loopholes for special interests, etc.), so they focus their efforts not on defending transgender people, but in trying to attack what they see as the real issues. A small minority of "people in charge in the U.S." are transgender, or very concerned with transgender issues, and are doing everything they can to fight for transgender rights.

Don't forget that the majority of the "people in charge in the U.S." are over 60 years old, and so even basic gay rights are a major departure from the world they were raised in.
