i think you're getting the wrong picture about israel
it's actually very accepted here just as it is in other places, there's a parade every year and everything. But just like relegious catholics dont accept it, relegious jews dont either
plus, gay ppl dont really flaunt that fact and start making out in the middle of the street, especially not in jerusalem. Maybe in tel aviv...
and well, as much as it is accepted, parents will always deny it :/
she probably always imagined u meeting a guy, getting married, having kids- the "accepted way"... so parents will always try to push u the other way, i think
but in the end she only wants u to be happy :)
