Is it rude to keep playing in a lost position?
This also is not rude, and some chess coaches even encourage their students to always play to checkmate, not only for the learning experience, but because beginners often blunder, and you never know when your opponent might mess up!
What IS rude, is stalling. This is when someone who is in a lost position delays the game as long as possible to make the other player wait! As long as you are not doing this, you can feel free to play on, or resign, whichever you decide!

Is it rude to refuse a rematch request?
Many players enjoy playing two matches—one as White and one as Black—against each opponent. However, there’s no rule that says you must accept a rematch request.
When sending a rematch request, remember that accepting it is entirely optional. A decline or no response isn’t necessarily a sign of rudeness or your opponent 'running away'—players have different motivations and preferences for their chess experience. Some might not accept due to not having enough time, being tired after several games, or preferring to analyze their mistakes right after a match.
If your rematch request isn’t accepted, don’t worry! There are countless other opponents ready to play. Just hit that 'Play' button and enjoy the game!
