I hear both words played at the same time. Yanny is high pitched, Laurel is low pitched.
The word "Church" itself is defined "Called out ones" The church that Jesus said the gates of hell would never prevail against is NOT a human institution, rather it is the temple built WITHOUT human hands, made up of the men and women God has called out for Himself to Christ. Past, present, and future.
Yes, both are played simultaneously, one filtered to let high frequencies through, one filtered to let low frequencies through.
It's disgusting, and there will be hell to pay for the perps. It's a drop in the bucked compared to the thousands of children slaughtered in the womb daily though.
