I agree, ghosting is necessary in many situations. Am a guy, have reluctantly ghosted both men and women (from a casual friend / professional point of view, rather than romantic) not because I think I’ll be yelled at (or worse) but if the vibe is wrong, it’s self protection - I don’t want to engage with them, full stop.
After a couple of bad questions, I’ll either excuse myself, suggest we carry on separately, or (ideally) ask to be sent a list, for me to ignore at my leisure.
Sorry Greg, we’re not here to answer your dumbass questions, or indulge your hypothetical edge cases.
