Diversity is opposing ideologically Fascism, because Fascism is uniformity of ideas and purpose (e.g. Rule of Law?). Thus the Fasces is the symbolism is what tells you whether a group is fascist or not. Fasces are made from a bundle of identical sticks all tied up in a bundle with an axe head placed amidst them. The military is a fascist organization, a cult can be a fascist organization.

What happened though is that it began to be used by radicals without a self reflection among its members, who cannot determine what the word actually means and why it is on so many flag emblems. So they unironically all start wearing black hoods and enforcing a same style of thought, unaware that they've been indoctrinated into a fascist organization. Diversity where acceptance lest you be labeled a "bad word" is bullshit, and it's very virtue signalling as opposed to actual facts.

Reject the attempts to coerce your society by bad actors in the state, they do not have your interests at heart.
