When I see a swastika or something like a totenkopf, my initial thoughts are of those from one side of my family who I've been told died because of the people that used these symbols. So I'm rather hostile towards them.
Some from that side of my genealogy were imprisoned and/or starved by people who used different symbols. So I'm rather hostile to that imagery too.
I see it around so much, and I wonder why it's acceptable. I equate the hammer & sickle with death, like the swastika.
