Is not resigning until mate a good policy?

You do have a right to be checkmated. It might be in the Constitution somewhere. But it is disrespectful. And I am sick of irritating kids making me prove that I know how to deliver checkmate. If someone says they always play to mate, or extends a game for 30 moves being a queen down, I just block them. I don't want to play against that kind of person.

@sparowe14 I really shouldn't play devil's advocate like this, but: if you're up a queen and the game still takes another 30 moves to reach checkmate, then either your opponent must have been putting up some stern resistance, or you were playing pretty badly; either way, the fact that the game continued like that vindicates their reluctance to resign. Clearly there were still chances, it just so happened that on that occasion, either you managed to control their counterplay well enough (so the game was still interesting), or else you just managed not to blunder too badly; on the next occasion it might be different.

@biscuitfiend funny, when I wrote that I thought, 'now some smart guy is going to say, well if it took 30 moves, then it must have been playable.' some people just want to keep arguing. I know I can't make anyone resign. I got it. But you can't change the way I feel about it either. It's bad sportsmanship to have that as a "policy." (That was the OP question.) You keep saying it depends on the position. Correct, of course. But a 'policy' to 'always' play until mating is infantile oppositional defiance, a refusal to accept the obvious result.
Admittedly it is fun to actually play the mating move. Sometimes it is good sportsmanship to let the winner show how.
Maybe I can find some games and send them to you to demonstrate my attitude.

Anyone complaining about toxic community but at the same time refuses to show good sportsmanship is a hypocrite. We evolve as a society by building ethical code, behavioral standards outside of the minimum set by the law or by the rules of the game.

@sparowe14 You are right. "Never resign" is a pretty sour policy (it is, however, quite humorous to watch Eric Rosen catch his opponent in a premove). On that we can agree.

In the example you sent me, I would have resigned as Black long before your opponent did.

@sparowe14 I agree with biscuit that if you're up a full queen, and it takes you 30 moves to win the game, then your opponent is completely justified in not resigning. If you're so good at winning won positions, why does it annoy you at all that your opponent doesn't resign? I'd say it's a lot more childish to block someone for making you play out a game than playing out a game until mate. Magnus Carlsen has had countless classical games where he has been completely lost, but he continued playing and managed to save the half point, or even win in a few cases. He became world champion by playing out drawn endgames and squeezing out wins. So according to your logic, Magnus Carlsen is a bad sport.

It should be fine. Do you stop drinking at a bar before you find a mate to leave with?

During OTB games....people will generally get upset when you try to resign even when you have no chance. This is b/c people like experiencing being in a position of power b/c they are pathetic people. During online games. I would say for your first 2 months of playing, make it a policy to never resign. After that, if you wanna resign after careful consideration....go ahead. Time is precious.

It really depends on who you are playing against. For example, if you are playing against a beginner and losing (under 1200), anything can happen. They may blunder their queen in a completely winning queen and king vs king endgame. On the other hand, the chances are that experienced players (1500/1600 above), the chances of winning a losing position (a queen and king vs a king) is extremely unlikely. The higher you go up the rating ladder, the more unlikely it will be to win a losing position from a blunder. In my opinion, resigning is a better option if you are completely losing a game as it saves you more time and also prevents you from the shame of being checkmated.

I think that in an arena tournament, this is a good policy because you not only waste your opponents time you waste yours, however in swiss it is fine as there is no time limit and anything could happen.
