You guys are giving way too much thought to the matter. I see this in my church. A LOT. There’s more talk about what to do and how to do it than there is actual doing.
There’s no need to be “covert;” no one’s sneaking into the Third Reich. If people want to stop being privileged in this instance, stand the hell up and say/do something when the time calls for it. This isn’t the world of Dr. Seuss. We’re not Sneetches who can have stars removed or applied.
If you want to wear a pin, wear it.
If you don’t, don’t. It’s a choice. That’s a part of the privilege white people have. People of color, the marginalized, etc. don’t get a choice as to when they will pick up or put down the trait about them that makes them the object of someone’s disdain.
For God’s sake all anyone has to do is simply BE YOURSELF AND ENGAGED IN THE MOMENT regardless of whether you wear a safety pin or not. You’ll know if it’s your time to the tip of the spear or not.
