“ I take no issue with that people want to wear them, what I do take issue with is that their activism stops at the pin.”
First, what are you basing that on? Why are you so sure this is true?
Second, for some people it’s a first step. It feels good to take action in defense of others, even it’s something really tiny (and that’s a good thing!), and there will be people who like how that feels and want to find out how to do more. But if you question their motives, many good people are likely to just turn off because they can never get it right (you’re welcome to judge that reaction, but it doesn’t change the reality of it).
Third, sure, maybe some people are just doing it as a feel good gesture and a trend. I’m not saying that’s not problematic — it’s good to remind people that wearing the pin has to mean being willing to back it up with action if you witness harassment — but it doesn’t tarnish everyone else. To me that logic is like saying that we shouldn’t have welfare at all because some people will cheat. It’s frustrating that there’s cheaters, but you don’t base your whole policy on them.
