People are wearing safety pins as a symbol that they are a safe and supporting person for minorities, both visible and invisible.
That's cool... but if you put it on, be prepared to follow through with action. We don't need another White People Feel-good Symbol. We need to step up and support folks who are being harassed whenever and wherever we see it.
Try to understand the frustration coming from minorities about the meaningless support symbol problem. They have seen symbolic gestures that are not followed by action over and over again, and they have every right to voice their frustrations. So display your symbols if you want, but more importantly, ACT in accordance with them.
Some people are worried that the alt-right is co-opting the safety pin symbol. Look, you can always modify yours to make it clear what you are supporting. Add rainbow beads, or a white rose, or both. Symbols of support to let people know they are not alone in a crowd are good. But the VERY BEST WAY to show that is to step in when those people need you to.
I am a passing cis hetero White Person, and I will step in. My pin is not to make me feel better. It is to remind me of my promise and to tell you that I have made it. Feel free to tell me if you see me not following through; real friends don't give us a pass when we are failing.
