I headcanon her as demi-agender, doesn't care what pronouns you call her. :-)

I personally think that Haruhi would probably use He/They pronouns- BEFORE ANYONE TRIES TO FIGHT ME- it’s my personal headcanon :’>

WHY DOES THAT SEEM SO REAL THO! tamaki aint bating the homosexual allegations w this one lolll

Anyone who visits this wiki is free to have personal beliefs, however; in canon, Haruhi is a bona-fide, self-admitted non-conforming FEMALE and there is nothing to cite that points to the club as being homosexual except Tamaki's joke.
