The purpose of the consent form is that it invites a player to bring these subjects and situations to your attention, so that you will have advance notice ahead of time and making it easier for you to accommodate them (if possible) or to suggest the player join another session if not.
I get that. And I'm telling you that when I run games at conventions or game stores I write the scenarios well in advanced, I don't know who will be playing when I arrive, and they are very often strangers. So advanced notice in these cases might be 10 minutes. It is unreasonable for anyone to expect me to make major changes on short notice.
As opposed to it cropping up in the middle of your session, making the player miserable, and then you having to adjust for the fact that one of your PCs has left the game.
It is the responsibility of the player to bring this up before the game starts.
