When is resigning just bad sportsmanship?

I believe it is because your quitting because your only losing. It isn't fair to the other guy for the fact that they came to play a full game of chess.

futile resistance is a sign of worse sportsmanship just saying

Resigning is a sign of saying: well you outplayed me i lost you were better.

Of course you quit when you're losing! Why would you keep on playing when you know you're going to lose no matter what?

Solutions played out: The game continues in positions where a player thinks that there is still some possible solution to save the half point by a draw. The player should consider resigning, when the horizon shows no way of saving the half point. If all options have been played out, a player must consider that the only appropriate action is to resign gracefully from the present match.

Resigning is never poor sportsmanship, just as playing it out to the checkmate is not poor sportsmanship either. The game is the game.

The only cases that qualify as poor sportsmanship are abandoning a game in progress (although this could be considered a form of resignation), using insults, or flipping the board over in anger.

Yeah resigning early is showing respect for your opponent and is most of the time appreciated.

The only thing that annoys me is when instead of resinging they let their clock run down after they blundered something and you have to site there and wait it out.

It's not a matter of their sportsmanship, but rather your psychology. If you play chess to "play a full game" rather than "to win" I suggest you play more difficult opponents or pick more drawish lines.

In many games (especially variant chess), it can feel satisfying to give checkmate, blow up the enemy king, give up your last piece, etc. So if you've played a game and you find yourself only one move away from losing, play your last move and let your opponent checkmate you. Then you give your opponent the satisfaction of winning without wasting too much of their time.

However, if you're more than a few moves from losing (e.g. if your king is getting surrounded by enemy pieces, or if you just lost your queen but opponent has no clear win, or if your opponent has a forced mate in 10), then it's better to just resign. Then you're not wasting your opponent's time playing an obviously won game, which is good sportsmanship.
