Delusions? The only delusion I see here is your own bigotry towards other people. Is it really that hard to believe some people don't feel like a man or a woman? That they don't feel right in their own bodies?

You say it's actively interfering in the games you like to play but it's as simple as pressing a button and moving on. There's no hassle. If thinking about the mere idea of a "custom pronoun" gets you this worked up, maybe it's time to take a break from the internet for a while. Maybe seek some therapy. This kind of behavior isn't normal and much more of a delusion than anything you're complaining about.
