This saga has showed the hypocrisy of our people, no problem at all with all the shameless dancing in public with filthy music holding hands while bump & grinding to the rest of the world, but go crazy over a kiss.
From a religious perspective the greatest sin on display is the "mixed wedding" itself, followed by the shameless music & dancing, all of this is far worse then that kiss, it's not even close.
Because those who paid for this and made this mixed wedding happen, will carry the sins of every male/female in that hall that dance with each other, glance at each other, hook up with each other, as well as all those people exposed to this music for the first time and as a result download it to listen to for the next decade or so, they will carry all these burden because they perpetuated this fitnah.
The kiss itself is nothing in comparison to all of that, with or without the kiss there is no barakah is such a marriage
The punishment for this would usually arrive in this world through divorce, hardship, broken homes, depression, stress, anxieties, disobedient children etc.
Hence why broken homes are an epidemic because they all started out on these same shameless immoral irreligious footing.
