Please go armed with the facts. There are numerous studies that demonstrate the harm posed by masks, particularly to children. Bring hard copies with you and read from them, if necessary. BE PREPARED. It is easy to get emotional where kids are concerned, but you are most likely dealing with a 'muh science' group and you want to give them the science. If they ignore it and say they are going with Fraudci or the CDC, tell them you are going with the science of the numerous studies you have brought. (If you need help finding those, check with 20-guage for a start - s/he may have some.)

Also, when people ignore the oath they took to the Constitution, they have 'vacated' their position. They can and should be removed.
