Is it objectively wrong to require women to cover their faces?

By "force" I am assuming you mean through coercion i.e., threats/violence. However, actions devoid of context become little more than ideas. And even though I am fairly confident as to what kind of situation you are implying, ideas are in and of themselves neither good nor evil (e.g., violence being used for good by a vigilante against a fascist regime or peaceful protests being used for evil by a supremacist organization against an equality law). Furthermore, it is my opinion that this concept of right and wrong is essentially what we as humans use as a quick and easy method of explaining to the vast majority of people important information that is either so complicated that they're too stupid to understand it or so time consuming that they're too lethargic to even bother trying. And although this tends to result in large groups of peoples paraphrasing the poorly worded arguments of some charismatic authority figure, any specific circumstance that we mistaken for right or wrong or something in-between can always be adjusted if and when necessary by future generations (e.g., if new information contradicts any preconceived notions or if there is a paradigm shift in how society views certain behaviors). It is this characteristic of "ethical vicissitude" that distinguishes it as an ideological construct of the human psyche and therefore a subjective quality. In conclusion, forcibly requiring women to cover their faces with veils is intrinsically neither right nor wrong as it depends on the situation (e.g. forcing your newborn daughter to cover her face while in heavily populated city is in my opinion the right thing to do). Additionally, if I were to assume a hostile situation similar to what is reported on the news then yes that would be wrong, but it still wouldn't be objectively wrong.
