One isn't attempting to draw a direct comparison to the actual victims of genocide and equate them as being the same thing as opposition and regulation of groups that are in no way oppressed whatsoever?
There's comparisons to be made, I don't know this was the specific intent of whoever designed the thing since I don't read minds.
The Nazis, from what I recall, one of the first things they did is to make it illegal for Jews to own guns.
This is obviously a protest to a government limiting the rights of it citizens.
Other comparisons you want to make, that's fine but personally I don't know any of that was intended.
