I do not do this, but I'm curious none-the-less.
Do you differentiate between those who wear SF items (belt buckles for example) to pass as SF and those who may wear SF items so that when asked, can express respect but not membership?

. I hope I am doing a service regarding awareness by stimulating conversation of an often undiagnosed problem.
