To my way of thinking, it isn’t so much of an insult as it is incorrect and misleading. Also it isn’t something that we would want to get stuck in the vocabulary of anti-trans folks. Clearly their thought process is that people become gay or trans and that it can be reversed, but that is patently not true. Several years ago there was an open letter put out by a number of people who formerly founded and/or led ex-gay organizations. They left or closed those organizations when they realized that they were causing more harm than good. The conclusion was that sexual orientation and gender identity were innate and couldn’t be changed.
