If you make it as literal and obvious that there is zero shadow of doubt, then sure. Like make Frieren a literal communist who says she's a communist while wearing a red cape thats held on with a ham-sic brooch while exploding demons dressed like nazis or wearing Klan hoods, etc. Otherwise any sort of layer of depth allows for the viewer to apply their own worldview to what they're seeing instead of whatever the artist's intent may be.
