No, a bisexual woman with her bf at pride is not hurting anyone,if anything it shows that queer ppl exist in different fronts.
and that bf could also be queer,trans, nonbinary,ace/aro, intersex or also bi whatever
bisexual who only dated the same gender, bisexuals who only dated the opposite gender, bisexuals who dated many genders, bisexuals who never dated anyone. They all deserve a happy pride month, stop being biphobic.
