"The original was stalemate is a win."
Only if you consider shatranj and Medieval protochess actual Chess. It was changed because the goal went from Baring the King to Checkmate. After that, Stalemate was, in most countries, from the start of the 17th century on either a draw or a Loss for the one stalemating (not a win). The big argument about Stalemate in the end of the 18th century into the 19th was to make Stalemate simply and logically a draw rather than a win for the stalemated side. The real purpose of all the debating going on in the 19th century was standardization so everyone everywhere played under similar rules. Gatherings of great chess minds such as Petroff, Jaenisch, v. d. Lasa and the rest of the Pleiedes, Staunton, Fiske and others argued and debated the reasoning behind all rules that needed attention and left us with a legacy that has more or less held up for a century and a half.
Why dont the people who dont like the rules of chess just play something else ? In checkers if you stalemate your opponent you win ! Try checkers !?
The chess you are playing and arguing for now is a variant.
The original was stalemate is a win. Why was it changed?
When we change it back, you can go play checkers.
