I think perhaps everyone could refrain from criticizing eachother. I think we all know that wasting/killing time and viewing immorality are wrong things (obviously the 2nd one much worse).
No orthodox Jew would condone having a immoral magazine with some ok pages on their coffee table.
Television and the internet both have that component to them. Many kosher things juxaposed with unkoshe. You just turn the page and it’s right there. A person can make the choice to only look at what’s ok, but that’s a tremendous challenge for many. Rabbonim feel the risks are too great to ignore.
I don’t think Rabbi Miller would say someone who uses television/internet in a “kosher way” only has lost his olam haba, but he’s certainly risking his olam habba and if not his than that of his family.
I think we all have to be open minded and courageous enough to realize these risks and take appropriate measures accordingly. And work to improve each and our own madreiga to avoid these things depending on where we are holding. But no one can bury their head in the sand and say there are no very serious risks.
Quoting that the Rav had a television doesn’t mean he approved on the immorality on it, and if he was living today I imagine he’d come up with guidelines for internet/television use for his followers. Although he may have not struggled with the desire to view inappropriate things and waste time too, he would understand that many would have such struggles.
We should all be zocheh to improve in these areas – no matter where we come from without trying to put others down!!
