Stalemate becoming a draw needs to be removed. It's a cheap gimmick that only allows inferior players to deus ex machina what would of otherwise been a loss from a superior player, into another boring draw.... I didn't even know this rule existed when I first started playing and it's making it hard for me to continue learning and playing.
The endgame is always extremely irritating because of this. I know some people are going to say "get good, learn the rules, this is a beginner problem only".
Yeah well. I can choose to TOLERATE this terrible rule, or quit, but it shouldn't be like that. Give players the choice on what ruleset they want to play....
No, the hard facts are only beginners whine about this. There is a true art to stalemate.
I actually had this position against a master over the board in March.
He played 1.f5??
This allowed 1...Rxc7!! and the game was drawn. He obviously did not take the Rook. He played 2.Rg8 Rc2 (threat of 3...Rxg2). I think he went 3.Kh3, but once he played g4, the King was stalemated again and I had what is known as the Eternal Rook Draw where I check the White King until he takes the Rook and stalemate.
In fact, I think the moves were 3.Kh3 Rf2 4.g4 Rf3+ 5.Kg2 Rg3+ 6.Kf2 Rf3+ and White then offered the draw seeing I just contine to check on the 3rd rank.
Stalemate is an art, not a cheap trick.

and no it is stupid because the person who was losing was just lucky that the other side blundered a stalemate and after all, chess is no luck game
Stalemate is not luck, unless it happens by accident in a beginner vs. beginner game. And even then it is questionable whether it is luck or just that the player with the material advantage was such a weak player that they stalemated the opponent and did not deserve the win. One does not deserve to win at chess before they can perform a checkmate afterall.
There are endgames like the most basic K vs. K + pawn endgame where the weaker side has the opposition and can draw because of that. It is not luck and the weaker side does need to know what they are doing in order to be able to draw.
There are a lot more endgames like this, but I am not going to try to list them here.
