I had a different experience for what it's worth.
Our Assembly was held at the Hunts Point facility in the Bronx N.Y. Black folks were the mainstay of the JW KH's and field service in that area soon to join with Spanish Friends.
Now I came from an Italian family and my mother was some what outspoken against Jews and Blacks for reasons she could never articulate.
At the age of 16 and newly Baptized I attended this Circuit Assembly. It was considerably over crowded...... they had folding chairs on every space possible. When there was a break in the talks I got up, like just about everyone in attendance, to stretch my legs and or seek a bathroom.
You couldn't stride down a proper aisle you could only walk in back of someone with no more then a couple of inches of separation. Under normal circumstances you could have been arrested for unlawful contact.
I'd never been crammed into a crowd like this. Moving with the crowd, It was belly to butt, always a black brother or sister urging me along. Having been warned by Mom that black folks smelled I wasn't sure what I would be getting into.
What I smelled was soap, talc, a bit of perfume and cologne. We were pressed together at times. It was intimate......... there was a lot of physical contact. It was hot with no air conditioning.....All in all It was one of my great memories.
In the years to follow I never once smelled anything inappropriate when attending a KH, Assembly, riding in a car for service etc. from any JW from any race.
