I do think that a lot of people are quick to dismiss flagging membership and the value therein.
People don't understand why people wear union pins all of the time, for example. We've also forgotten how this has been used historically.
But on the other hand, I _also_ find that a lot of people think that they can put on a bracelet or slap "part of the Resistance™" in their bio and call it a day.
There's a balance.
