The Germans really don’t know what to do with the Start of David.
When they are not making Jews wear them on public, they are telling them not to wear them in public.
Outward displays of being Jewish (wearing a Yarmulke or other identifiable Jewish religious item) is angering Muslim migrants in German cities and has provoked attacks on German Jews.
And this is why I carry.
I have a Star of David I’ll be happy to display for them.
Consider it a warning.
