Arnold actually addressed this very close to when he said it, though I thought it was pretty obvious what he meant.
Basically said in these times if I'm asked to wear a mask in a shop or wherever I'll do it as it's not really affecting freedom to get through this, he was talking as we as in everyone.
I don't think that statement was about the vaccine too...
I never agreed with him about the vaccine but wasn't about to throw out my original arnold strong muscle building pamphlets.
