The bad in this would be a young black girl trying to bring her hispanic friend. Exclusion is exclusion.
If this were the WhiteBoysSew club, you would call it racist, despite the fact that very few white boys learn to sew.
exclusion != racism. Racism has power dynamics associated with it. If exclusion (or special inclusion programs as I would call it) leads to a more racially and gender balanced community it is a good thing.
Whether or not something is good has nothing to do with what it's labeled. Sure by definition it might not be racist but certainly that's how it would play out. A better equation might be:
There actually are groups like that for areas where men are historically underrepresented, such as the American Assembly for Men in Nursing (http://aamn.org/). As far as I know they don't get a lot of flak.
With white people in specific there is a bit of eyebrow-raising, because "white" is a bit broad, a historically dominant group (in the U.S.), and has some history of "white organizations" being intended mainly for exclusionary purposes. Despite being white myself, I would probably be skeptical of the intentions of someone who asked me to join an organization with "white" in the name. More specific organizations targeting subsets of white people are common, though. For example, there are scholarship programs for Americans of Greek ancestry. There are also a number of initiatives targeting "Rural Appalachians", which is not definitionally white, but is almost exclusively an identity held by white people.

Lots this non-Anglos weren't considered white back in the day. JFK was asked if his being Catholic would hinder him.
