Ujm, Sorry, didn’t reply to your post before. On those who walk bareheaded, I am all for helping them out and I am all for organizations and individuals who help them. I don’t think berating them would work.
As for fedora, my family minhag is to dress up like respectful members of current society, so I have no problem with others doing the same. My great greatzeidi dressed like a Vienna businessman, and I dress as a Midwestern businessman and it is all fine.
