If not actively persecuted, there was a time when anyone who questioned the status quo faced discrimination, especially if they published their ideas. I can't see that happening again here but, as Maeght says, "Who knows?". It's up to us and our descendants to make sure the ethos of (relative) free speech and religious freedom, including the freedom to not adhere to a religion, continues. A diverse and tolerant society is one to be cherished.
