Gadol, happens to be that when i worked in an office for a short time, it was gender separate! Many frum businesses do this.
Nom – glad we can occasionally have a level headed discussion; sorry if i upped the temperature unnecessarily.
Re, kedushah meaning separation; see Rashi on “ayeh hakadesha asher ba’ayin”, rav hirsch in chorev discusses the definition of kedushah this way too; i can find mekoros if necessary.
The gemara about abayah is sukkah 52b; rava is not there, i made a mistake.
As for what I’m trying to say – I’ll clarify. Of course it’s not a good idea to look for nisyonos or to get one’s self to notice things unnecessarily. The baalei mussar say that if you’re walking on the street and constantly thinking about the nisyonos of shmiras aynayim, you’re likely to fail – being masiach daas from it is very important.
But I’m not saying not to be masiach daas. I’m referring to a cavalier attitude many have which is that they can look anywhere and not violate halacha, because they’re mature enough to control themselves. To that, i brought gemaros that no one can say that they can control themselves, and therefore they must keep themselves away from nisyonos as much as possible. When actually confronted with the yatzer hora, the game plan is like you said, to ignore it.
When I said that we’re supposed to be repulsed by bad sights, it’s something that happens by itself when you’re distant from them. When i spent the entire summer in camp, and hadn’t been around goyim for so long, it hit me much harder when i came back to the city – that’s a level of sensitivity and kedushah. That doesn’t mean i drove myself crazy and tried to notice everything; it’s a madrega that happens memaylah.
As for news site ads; i don’t see them, i have a pop up blocker and my filter cuts out most of them on the page.
