WAH!
Opponent is forcing a draw per repetition

Winning in chess includes not letting yourself get in a position where a draw by repetition can occur.
It's like complaining that one team got more goal shots but lost just because of a better goalie even though the rest of the goalie's team weren't very good, so the team with the most shots at the goal should win.
It's NOT good enough in football/soccer/hockey/etc. and it's NOT good enough in chess if you can't avoid a 3x repetition.

something even worse happened to me. i was having a good game and won a minor piece because he blundered but then a few moves later he checkmated me. how dare he win this is happened
for those without eyes i can confirm that i'm making a joke about the OP's stupidity. that the opponent is merely trying to get the best out of a lost position. in reality he should've played better and stopped it from happening. i request that he change the title to "my opponent is drawing a lost position because i'm playing badly!"
I changed the color of the text there for those who have poor eyesight like me...
+ if the people who you made that part for had no eyes why did you make it white?

Chess was created when people still ate with their hands and died from the plague. This rule is as old as the one where they chopped your head off for mocking the King. Please. These rules should have been updated years ago.
The first time the rule was made official was 1883 in a tournament in London.

You blundered when you castled allowing your opponent to check you.
You had no complaints when he blundered and you capitalised so why should the converse be any different.
