I don't think that this is true, actually.
I only read good things about her for instance that she was very friendly to the press and to the fans in Malmö! Remember Esma herself is part of a minority group, it seems very unrealistic that an open minded woman like her says something like that!
BTW I also read that she even sang on a gay wedding some years ago .... would a homophobic person do that ?
Naaaahhh this seems like bad press ...not more not less.
And anyway how can someone dislike gay people ? They are as "normal" and lovely as straight people for me (a straight guy) !
Don't believe all the roumors, Guuuurls.
