@quasi @lxo @mjg59 If you don't understand why the framing of that questions is intensely transphobic, and as a result intensely harmful, then I invite you to reflect on that and find a way to be kinder to the people you share this planet with.
Setting that aside, though, yes, policing basic bodily functions like urination and defecation based on your personal assumptions about how other people's bodies work is an encroachment on bodily autonomy.
