Good on you, keep at it as long as you are able, those who are in danger and stuck in the most dangerous places need to see someone sticking up for them the most. ✊
Living in Florida with two youngins, I can't risk it. Some unpermitted asshat will blow me away without so much as a word. My wife has a banned books shirt and an Alt NPS shirt, and I worry. I have some science shirts and a Reading Rainbow (unofficial) books shirt, and I'm just waiting for a confrontation. It's as far as I can risk.
How does a wearing a shirt help me beat them? Does it pass legislation? Does it organize protests? Does it unionize or strike?
It sounds like you want me to endanger myself for no good reason instead of doing something meaningful. Give me a break. I'm not cowing. I'm simply not taking unnecessary risks THAT WILL DO NOTHING.
