Not saying I have the answers, but I typically attack the person’s desire for oversimplification and binary stupidity. Like, “Do you feel like this question encompasses all bathroom related issues?” It gives me the time to think, while also assessing their vulnerabilities from an unexpected redirection. I ultimately attack their confidence in forming questions by adding edge case exceptions to their simplified outlook.

When someone poses a question like this, the are telling you that they lack depth. They do not have a good grasp of scales or complexity. They also lack the self awareness required to effectively empathize with others. This is a vulnerability that they have exposed. By exploiting this vulnerability, you invalidate their argument, take control of the rhetoric, and you increase the chance that their insecurity motivates growth of their self awareness at some later point.
