Is "mick" a racist term?

If it was anything it would be an ethnic slur. As with most things context is everything. Mick itself is rather innocuous and more found in jest or an endearing form of Michael. Where such anti Irish sentiment has any relevance/power, it isnt the preferred term of abuse anyway.  So No.

This.  It's not racist, but it is nativist.

I'm about half-Irish by ancestry and if it's meant to be pejorative or as a slur, then it is.  I don't like the term, but if you're using it as a nickname (like Mick Jagger, for example), then I have no problem with it.
