I always like when people in our party are so invested in finding new ways to pwn the fascists in the marketplace of ideas. I'm sure the fascists are doing the same in their 'self defence' classes they are talking about.
You seem to equate all of the Wehrmacht (which mainly consisted of very young conscripts, many of them malleable, uneducated and never having come in actual contact with people outside of their direct environment) with the horrible atrocities a powerful elite amongst then chose to carry out.
