Basically it’s all about guarding your eyes. I heard a TV is compared to Avodah Zarah and just like you wouldn’t bring a cross into your home, you shouldn’t bring a TV into your home. It is just very hard for some people to accept as they don’t see that TV or going to movies is a problem and refuse to accept that it will effect them, because most people eventually, forget what they saw, but it stays in the mind FOREVER. I grew up watching TV and wish, I had not seen the things I did.
