It is a shame if anyone did reject you because of that.
And a shame for them to say it, whether or not it was really the truth.
But, sadly, there are many stupid and worthless people in the world, and there just isn't enough time to worry too much about their many regrettable activities.
Just move on, protect yourself properly in future relationships, but continue to celebrate the world in all its diversity. That's
what life is for. Not for moaning and bitching about meaningless "preferences" ...
