The iPhone keyboard requires 2 taps for punctuation, including periods. Americans (and iirc especially younger ones) use more iPhones than Android phones (don’t know about other countries, but OP indicated in a comment that they’re in the US). I’m not some old guy saying the youngsters are just lazy, but I do think the iPhone keyboard is a factor in how text-based communication has evolved.
Pro-business/anti-regulation types teamed up with the anti-abortion types around 50 years ago in order to get votes for their unpopular ideas, then they did everything they could to conflate the two ideologies to where Christians (the dominant religious group) now think Republican=Christian=Republican and thus ALL Republican ideas intrinsically align with their religion. I.e., Jesus was a capitalist rather than anything that’s actually in the bible.
Tl;Dr: propaganda and the natural human tendency toward in-group bias.
