This response is not for all, but for some may help. When it comes to entities
(businesses, schools, homes, church, ...), I've followed these two small rules to deal with this all:
1. Their entity; their rules.
2. If I want what the entity has to offer, see rule #1.
We each choose how we emote on this (and any other) issue. I've been around long enough to learn that negative emotion is rarely helpful. If you want to participate, just go with it and don't waste any negative emotion on it.
I do not enjoy wearing masks; I do not believe in most of the mandates; I think many mandates, of government origin, are not legal. But when you're dealing with private organizations: their business/school/home/church, their rules.
