Allowing LGBT was a mistake.

Any and every instance of straying from Christian morality was a mistake. There is no such thing as "secular", something will always be worshiped and it's only a choice of whether you would rather it be good, or evil. Morality really is binary, and trying to find a so called happy medium has destroyed and degraded civilization itself.

How long until they declare it a crime to oppose their agenda publicly and charge you with hate crimes until you submit?

Several years ago. There's a teenager on trial for "murder" in Wisconsin right now for exactly that.
