Indigenous Summer?

 We're enjoying the traditional two weeks of beautiful summery November weather here in southern Ontario at the moment. We used to call it Indian Summer.

Is it still all right to refer to it in those crude terms? One never knows what those statue-toppling history revisionists are going to riot over these days.

How about aboriginal summer, guys? Does that suit your delicate, highly-evolved sensitivities any better?

Or, would it be even more suitable to refer to it as Indigenous Summer??

One can never be too casual with the terminology these days.
