Chicago is "a Catholic town," you say? Facts disagree. Your perception is not reality, Mr. Kass. According to Pew's survey in 2015, Chicago is 34% Catholic and 35% Protestant. The largest population is "no religion" — atheists and agnostics are 37% of the population. So, the reality is, saying "Chicago is not a religious town" would be more accurate than saying it's "a Catholic town."
