OK, but as one who collects military items as well, I have seen them selectively enforce this policy.
Here's what the ebay policy states:
"Examples of items that will generally be removed:
Items that bear symbols of the Nazis, the SS, or the KKK, including authentic German WWII memorabilia that bears such marks.
Crime scene photographs
Morgue shots
Letters and artwork from notorious murderers
Electric chairs and related capital punishment items"
Personally, I prefer "happy" chips, but this post caught my eye and I thought I'd throw my two cents in.
