Now, I've seen that the British Humanist Association markets t-shirts bearing their H logo, and the website of American Atheists sells, among other things pendants with their hydrogen atom symbol, worn just like a christian cross or crucifix, or a Star of David. Should those be banned in public places too? Or is that an attack on free thought and individual liberty?
If those items could be used to hide the identity of the wearer then yes, they would have to be prohibited in some public places.
