Is the wearing of hijab inherently at odds with women's rights/freedom?
No, it's just a clothing accessory that enhances privacy. There's no reason to infer that it is inherently counter to the interests of women's rights.
That they are usually forced to wear by either the government or their husband.
I don't think usually is an apt word to use to describe that. Usually people wear the hijab freely as a cultural practice. There are cases where people are forced to wear a hijab or, more plausibly, a burka, and those incidents are deplorable. However, we should not confuse the forced wearing of the hijab, which is inherently oppressive, with the traditional wearing of he hijab, which can be empowering. In a similar respect, purity rings in the West are empowering insofar as women choose to wear them and abide by their pledge. Like many things in the world, the hijab is a good thing insofar as women choose to wear it, which the most common scenario.
In fact, in many governments women are forced not to wear veils, which can be oppressive for Muslim women raised to value modesty.
It almost certainly is, except in the (presumably) exceedingly rare cases where wearing it is entirely her free choice, without ever having suffered any social pressure to do so, or being indoctrinated to believe doing so is necessary or even more "acceptable" than to not.
No. Not if its a choice. Catholic nuns wear habits, which cover about as much as hijabs.
No, no wearing of any particular article of clothing is inherently "pro" or "anti" anything.
Not if they choose to wear it.
No, but making the walk around in a black burka in the dessert heat is pretty bad.
It is if forced
No, unless forced.
But even if forced, it's only sexist if it's unequal, and in many Islamic countries where women are forced to dress conservatively, men do too.
the forced wearing, yes
