Hijab is a head covering so they cannot "pull this off their faces".
The wrongs of niqab and hijab cannot be justified by the health issue of face covering in a global pandemic. Bottom of the barrel logic!
If muslims had stayed tied to the rope of Allah, His Qur'an and only hadith and sunnah we should follow, then nobody could harm us; if they are being harmed then the top of the barrel logic tells you what?
