One practical bit of advice I'm going to give is that Canada has a asylum seeking track specifically for LGBTQ+ refugees. American LGBTQ people under threat from legislation made by the incoming administration would be eligible for that.

While having to leave your home is pretty unhappy and not always practicalsolution, I would encourage everyone LGBTQ+ in the U.S. to read up on the Canadian asylum process and make plans on paper to flee to Canada if/when it becomes apparent that it is necessary for their own safety. (Note: you should keep these plans secure and private. Only share them with specialists who you are seeking advice from, or people who would be fleeing with you. People you believe are friends or family today may become privately hostile to you in years to come)
I am hopeful that organisations that specialise in facilitating LGBTQ+ people fleeing persecution will pivot their efforts to the U.S. in the coming years for those who may not have the means themselves to relocate. I don't know which organisations these will be yet but hopefully they will present themselves in due time.

I wish that I were in the position of being able to say that things would not get to this point but I am afraid that the blunt truth is that it is a likely enough situation that it is worth preparing for.
