Everyone individually decides what feels objectifying. Objectification occurs when a person feels they have been treated more as an object than as a person, and when that is is different for different people.
There is not, by definition, an objective, fixed length list of things that are objectifying. It is up to us, both at the individual and at the social level to try to be more aware of the phenomenon of objectification and actively avoid it.
If you learned to empathize with others, like women, then you would be able to understand that your demand for the issue to be black and white is beyond unrealistic.
