Somewhere out there are honest-to-god Bourbonists but they do not have a material basis to exist as a major force.

Russian and russophilic fash still fly the imperial banner (thus keeping its meaning in memory as a symbol) but they will never reinstate tsarist feudalism, only fascism. The conditions for tsarism simply no longer exist. The coat of arms of the House of Bourbon on the other hand has not been widely used by the modern French far right. Bourbonism as a movement no longer exists. Thus it does not symbolise the white terror anymore, while the imperial banner does.

Roman symbolism exists in an in-between state where it is not necessarily the domain of imperialist reactionaries but remains in use by them.

The strongest reactionary monarchist movements, and thus those whose symbols still hold weight, are in places which still have monarchs (e.g. Ulster traitors, neo-falanguists).

This only really proves my point that symbols retaining hateful meaning do so through active use by hateful movements and that it only really loses its connotations when the movement is symbolises ceases to exist in a meaningful way.

We have fortunately gotten rid of many kings and removed the social basis of feudalism. However, Neo-Nazis persist today and seem likely to persist for a while longer. Their symbolism will remain known as such until the destruction of the basis of fascism.

At the very least he grew up Catholic
