Oh great guardian of the galaxy...
I took it differently. To me it was a message not to waste your breath in your personal life. It's one instance where you can find victory in surrender.
Believe it or not, I have acquaintances even here in Canada who are anti-vax, anti vaccine passport. They're not far removed from flat-earthers IMO. I try gentle persuasion but it's still a waste of time. As you get older you'll come to realize just how scarce time is.
If it floats your boat, keep up the good fight.
