A proper amount of cologne or perfume should be acceptable in about any setting, including the Kingdumb Hell. If someone is so allergic to fragrances that they can't be around normal people wearing normal amounts of scents, then they're the ones with the problem and they need to see a doctor.
If they can't sit in a Hall because of the scents, what about work or school or the metro or the restuarant, etc.?
And for elders to proclaim KHs as scent free zones is just more evidence of their pharisaical attitude. Yes, it would be loving and kind to be mindful of how much cologne/perfume we wear but to make rules and laws about it?
Now, on the other hand, I've seen some of the friends wear a half a bottle of smelly shit. And I ain't talking Obsession or Polo Sport. I'm talking High Karate or Old Spice. You could smell em from the parking lot. Those people needed some kind of counseling about how to properly wear cologne. I think some brothers used it to cover over that they were too damn lazy to take a shower before coming to the hall. So instead of plain ole fat guy BO, you got the nice pungent aroma of Old Spice and Horse Sweat. Slobby lazy bastards.
