My old person trait is that I think 'ghosting' is completely unacceptable and you owe the other person a face-to-face conversation.
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.
