“If halachic dinners became the norm, would that make them okay? ;)”
Haha, oy back to that again.
I was simply saying that its going to be very hard/impossible to enforce. The biggest current issue of this age in my opinion is damaging others through social media. People have ended their own lives because of this.
However, I dont think the couple has the halachic or moral right to demand that guests dont take photos of other guests at the wedding. There is a grey area in secular law regarding who owns wedding photos when it comes to professionals, but at least in secular law a non-professional guest at a wedding would certainly own the photo he took and can share it since there is no right-to-privacy at a wedding. But its certainly wrong to share it if the couple requests not to.
