Meld it with traditionally progressive symbols, though that’d take some effort it wouldn’t be too difficult so long as you effectively ran it by committee. For example something along the lines of having “Bash a Fash” in English, “Blòt them fast” in Futhark. Like I said it would take some effort but it could work, kinda like how quite a few Hellenic Neo-Pagans are explicitly progressive while Ultra-Orthadox eastern Orthodoxy is usually fascistic.

Mind you this does require some level of large scale action it shouldn’t be too hard at least here in the US. Most modern fascists, reactionaries, and conservatives wrap themselves in the cross so what better way than invoking Christendoms last large pagan foe.

Just a hypothetical example I’ve thought of, if protesting a mega church or Bible thumper dress up as a bunch of vikings and invoke Lindisfarne. Show up in a pick up with daneaxe in one hand a protest sign/shield in another, IDK just spitting ideas. Like I said it would have to be consistent and careful so as to not invite the wrong types on accident.

Also it’d be funny to sue the cops for taking a daneaxe on religious grounds.
