Rules vs. Immutable Laws of the Universe

I’m coming around to the single space after periods and colons. I’ve been persuaded that ending a sentence in a preposition won’t immediately result in a hail of fire and brimstone. I split infinitives with abandon. I can hardly restrain myself from using an em dash for parenthetical asides in every sentence I write. No matter how many dictionaries correct me, I will always spell it “judgement”.

But they will pry the Oxford Comma out of my cold, dead hand.
