People are highlighting how well she describes how allyship sometimes comes before coming out, but I also want to put emphasis on "... the guy takes off the earring, no-one was hurt."
Sometimes a person needs to explore and experiment before coming to the conclusion that actually they're not queer at all, and that's not only perfectly okay but - in my opinion - a brilliant thing to do!
There's a real risk of saying that a person who questions their sexuality will always turn out to be queer and/or if a person questions their sexuality and turns out to be straight after all then they were faking or attention-seeking.
Having the freedom to explore, question and identify your orientation/gender should not be a luxury permitted to only the minority - that then runs the risk of the very act of questioning becoming outing one's self.
It's similar to cis people wearing pronoun pins - if only trans people wore pronoun pins then the pin suddenly becomes a clear sign to the world that the wearer is trans, which not every trans person wants to broadcast.
I personally make a point to congratulate any cishet person I meet whom I know have taken the time to question their identity, not for being progressive but for having an understanding of their identity not because society told them what they are but because they determined that for themself.
