Are you sexualizing the seniors nudity or the kids viewing of non-sexual nudity? Either way I think you should see a shrink.
There are videos of dudes having sex on gay pride carts in broad day light in major cities.
Let's not pretend that the gay community isn't the most promiscuous community (stds stats, amount of partners stats, &c.) and that half naked dudes in bdsm outfit are "non-sexual". The whole thing is about "sexual liberation". It's not even about being gay or not, it's about decency, I'd have the same discourse for a "straight pride" with straight people having similar behaviors.
