Not sure ts disrespectful. While I wouldnt buy it and i can see why they dont find it fitting. But nothing about it disgraces the memory. If someone wishes to keep a memory of oppression close to them so they are reminded of it I have no problem with it.
I certainly dont think it is a clear enough case to call on amazon to outright ban it.
If it were a toilet seat cover or something then I could get behind this.
