re: HomeOwner
As righteous as their cause may have been, you’re watching people who do not have the gadlus nor the sensitivity of bnei Avraham, Yitzchak viYaakov.
Furthermore, they are actors who are being paid to convey a particular set of emotions and reactions. And that goes from the screen to your eyes to your soul.
And that lack of sensitivity (among other things) is bound to have an effect on you, as does everything in our seviva.
At the end of the day, one should filter what one allows into one’s body so that only purity and good is even brought up for consideration; that goes for all senses: sight, sound, taste, etc.
I can’t tell you it’s assur, but I can tell you that it makes no sense to make yourself a lesser person as a result of watching it.
