Glorifying soviet weapons doesn't equate glorifying communism, just because something was produced/invented by gommies doesn't mean that it should be despised.
I love soviet music even though I despise gommies.
And a lot of commie and post-commie guns are pretty aesthetic. (also S.T.A.L.K.E.R)
And /k/ isn't really leftist considering that majority of userbase are muricans, and murican lefties are anti-guns.
