isms of everything

Sectarianism, Buddhism,
Yorkshireisms and Fascism.

Pescetarianism, Terrorism,
Anarchism and Absurdism.

Commercialism, Elitism,
Humanism and Antagonism.

And the showpiece; Antiferromagnetism,
Along with all the other anti-isms.

I could go on for quite some time since
We're so ism'd up to the eyeballs here!

But You say you don't believe in them
And I think I must concur.
