What you are saying is to use the expression(s) as the currently active propaganda dictates and not explaining what they actually mean, and especially why they mean what they do in you local propaganda (which is just another name for the loudest mouth around).

Adding new symbols for established and widely known concepts can backfire, as the counterparty can easily muddy the new symbol by calling it the old symbol.

Im not saying, that those meanings are not true, you are right ofc, it’s just that education goes a long (or actually all) the way. Like, you basically can’t imagine western world without a swastika being a Nazi thing, yet that could have been the case.

Its always the victors that fud people (duh), eg its not like the French revolution was always seen as a good thing (or not just as killing and pillaging), it took years, decades even to become synonymous with freedoms(the non-™ kind).

If the revolution failed, the eg guillotine (or whatever) could have been commonly as hated as nazi swastika, not a thing little goth girls with loving parents play with.
