There are certain words (particularly Führer on its own) and phrases that modern Germans avoid due to Nazi associations, but Anschluss is absolutely not one of them. It's a common, general term.

Nor is "ausrotten", at least not in its literal meaning. I'm not sure about how appropriate its use for the figurative meaning is, but its connotations are pretty violent regardless of its Nazi use.

Thanks for the clarifications, I probably should have drawn clearer distinctions.
