Here's the thing... Most everyone makes mods with swasticas, so there is no "one" swastica modder. Just about all of us use it.
If by getting rid of swasticas, you mean on the flags and on the deck of the Bismarck, then I can do it easily. I can swap the swasticas for iron crusader crosses if you want.
Or I can blank out the entire swastica. Your choice.
I'll do it for you... Just give me a few specifics. Exactly which swasticas would you like removed?
