If you tried to discuss it with anyone you would be ridiculed and sometimes even physically threatened.
I don’t know if this is true. You can read plenty of early/mid 20th century books where characters will outright talk about how they don’t believe in a god. Sure certain areas you could get away with it more, but I think there has always been some prevailing strain of people just going along with the community aspect and not being a believer.
I tried to buy candy yesterday and the candy canes had already replaced the halloween candy. Awful.
