The Internet has a filter at the ISP level that prevents any sites that are not on the approved list. No TV has that. You C”V bring a TV into your home, you can be absolutely certain of the negative consequences both you and your family will inevitably suffer. Same with movies. Other — perhaps — than cartoons, no movie running in the theatures in the last 20 years have been kosher. Full of all the things I mentioned.
cinderella: At least you are on the level to admit that movies are a “big yeitzer hara”. Some people bury their head in the sand so deep they can’t even yet see that. Now you need just working on eliminating that yeitzer hara.
