This is a common trope in these topics. And I gotta say, to be perfectly honest, that I hate it.
Leftists/anti-fascists also rely on having face coverings to protect themselves from state repression, and doxxing from nazis, despite being right in their beliefs.
I get where you're coming from with the sentiment, I do. But rather than taking issue with the masks themselves, I'd recommend taking action (or at least encouraging it) and physically removing their masks so they can be properly doxxed themselves and face the consequences of their violent and hateful beliefs.
Edit: Case in point, here's a link to a video of the Proud Boys fighting with another, smaller, local neo Nazi group where they start to de-mask each other, towards the end of the video. They know that being exposed to the public is detrimental to their livelihoods, but will still do it to each other whenever there's a conflict.
Take note of that, and act accordingly.
I would cry if La Sirenita were to ever close.
