WHY DO I PLAY ANYMORE?

I WAS PLAYING A TOURNY TODAY I HAD K 10 OF DIAMONDS AND I FLOPPED FLUSH DRAW I BET OUT AND EVERY ONE FOLDED BUT TWO GUYS, THE TURN CAME IT WAS MY FLUSH I WENT ALL IN 9,000 CHIPS THE ONE GUY FOLDED THE OTHER CALLED HE ONLY HAD ABOUT 4,400 CHIPS HE FLIPS UP A 7 OFF SUIT NOT EVEN A PAIR THE RIVER COMES ANOTHER DIAMOND YOU CAN GUESS THAT ACE WAS A DIAMOND. FIRST OF ALL HOW DOES HE MAKE THAT CALL AND ALSO COULD HAVE I PLAYED IT DIFFERENTLY. WHY DOES OT SEEM LIKE EVERYTIME ONLINE POKER REWARDS THESES TYPE OF PLAYERS I WOULDNT NORMALLY SAY ANYTHING BUT IT HAS BECOME A DAILY THING SOMETIMES MORE THEN ONCE A DAY WHAT IS WRONG WITH ONLINE PLAERS? I HATE DONKEYS IT MAKES ME WANT TO QUIT POKER BECAUSE THERE ARE TOO MANY OF THESES PLAYERS OUT NOW EVERYTIME YOU SIT DOWN THERE IS ONE THERE.
