Mod80, I have a lot of respect for Daas Torah. I don’t have a lot of respect when people throw around things and just say no. I may disagree with logic of some Daas Torah (usually based on my Daas Torah), but that’s different IMO.
If we are really worried about teenagers viewing each other inappropriately, maybe they shouldn’t be invited to the wedding? In all seriousness here…because just by attending, in MOST places, they may see each other. Except in halls where they are basically seperate buildings.
