I agree with you. The hubris of the author is alarming.
An anecdote of my own: I grew up as a gay teenager. At some point while I was in high school, a trend caught on, where people would wear tiny rainbow pins similar to these pins to show their support for LGBT people.
Many students and faculty wore the little rainbow pins.
It was a tiny gesture on behalf of the people who chose to wear the ribbons (though, this was a high school; there was a certain amount of courage necessary for even a confident teenager to wear them around. It wasn’t uncommon to be called “gay” or something more crude for showing your support.)
But to myself and to many other closeted or nervous gay teens at the school, it made all the difference in the world.
That tiny little gesture showed that we were not alone, and that many faculty and peers were willing to openly demonstrate their support. It didn’t matter one bit whether or not they were trying to “dismantle heteronormativity” in some grand way or not. The ribbon alone was lovely and brave, and made me feel less alone and anxious.
The author of this piece positions her opinions as a universal truth that applies towards all oppressed peoples.
I for one strongly object to the arrogance of the inferring that she speaks for a whole group of people, and I condemn this sort of putting down eager would-be allies.
The author may get nothing out of allies wearing little pins. That’s very nice for her. But she is discounting the benefit or reprieve that potentially countless other people may get. Even something as small as a bit of anxiety reduction that they needed to get through their day.
