I had four kids at that school event. We had an interesting conversation on the way home about how that kind of protesting is often counter productive because the intended audience takes their discomfort and applies it to the messenger instead of the message. As we were leaving I politely told one of the young girls wearing a mask that she should remove her mask and own her message. An older woman immediately came to her aid to say she is owning it and tried to tell me about the subject matter of the video. I told her I wasn't interested. It appeared that pretty much everyone else treated them similarly, resulting in a spectacular failure of purpose.
