I disagree, DY. Though I am not claiming I am correct, but my thoughts would not apply to all cases.
The classic ??????? is Joe sees a women and stares at her due to her beauty (see the Rambam.)
If Joe is staring at a screen to watch the Jets (see people when they watch a screen it is ??????? mamish) and then a model comes on to tell him about the latest Potato Kugel from Pomengranate – is that the same? He didn’t want to stare at her – in fact, Joe is a religious guy after a moment, he’ll iy’H immediately turn away and try to take the said thought out of his mind. Mind you, it’ll cause damage – but same with going to work in the city – but its still muttar and not only that if one needs the parnassa – it is required. If one needs to relax and there are only activities that have women around improperly dressed (example the kids are in the house and freaking out and need to get out in the summer – everywhere there’s something). Perhaps (again I am asking academically not trying to prove so) it is allowed to go out to the Bronx Zoo on Chol Ha’Moed Pesach. Efshar.
It is better to work in a frum environment. Agreed. But it’s not assur to not do so. It could be that if there is no viable Kosher entertainment, the same would apply (again assuming the video is not l’shem tznus [see sports game] and assuming that there is a need for relaxation). One watches their son’s chasuna video it’s not l’shem tznus – agav they see something, it’s not a good thing but it doesn’t make the action assuer (perhaps). Same with someone who is watching an action movie to see the special effects not to see the actress in a revealing situation.
I think its a stretch to say Joe is in Rambam’s category. Do you see my distinction?
