I mean, if a household that keeps kosher has two sets of everything (plateware, silverware, sinks, etc) to make sure meat doesn’t touch dairy…the logic states you should have a different machine/method for excrement-related things to ensure it doesn’t touch your normal plateware and silverware.
I, personally, would not be comfortable using the machine again for food related things if I found out my housemate had washed the toilet brush in our dishwasher. Poop is meant to be expelled from your body, not consumed in any way - may I remind (the royal) you how pink eye originates?
I agree, and I believe OP does too, but I read their post as “since we live in a world where trans people can’t 100% feel safe or want to post the fact that they are trans, and we end up dating and I later find out they are trans and I did not want this in a partner, now we’ve wasted everyone’s time when it could have been addressed from the get-go.” I believe OP is trying to discuss what the best way of putting this preference on your profile without straight up saying “no trans people”.
