Tbh, I haven't read/watched much of explicitely far-right art but that sounds reasonable. IIRC nazis (as in NSDAP and whoever made art during that time) heavily focused on the idea of vitality, physicality, health, and the beauty of masculine strength which sounds like it is almost destined to produce homoerotic effect. I mean, if you encourage men to depict beautiful male bodies, you will get depictions from and for men who are really, realy into beautiful male bodies. :D
