I share your outrage, and I (regrettably) got vaxxed before I understood what was going on. I refuse to patronize any establishment that requires "proof of vaccination" for entry, even though I have a stupid card. I wonder if your favorite theater in Northern California is the one in Berkeley that has been infuriating me with their crazy entrance rules (I keep checking their emails to see if they've regained their sanity—just out of curiosity, not that a rule change would end my boycott). Solidarity!
