You really can't go anywhere online in the last 10 years without lefty circles using the term "Nazi" indiscriminately to refer to policies that the right-wing supports, such as decreased immigration. So when you get marketing for a Nazi-killing game that directly references, or at the very least, leans into the contemporary politics of the times, it's no surprise that you're going to draw ire. It's a really shitty thing to do for a series that was never political in the past.
