When I started my current job I was the only white person in engineering. The reason that it makes no sense to have a "white male" group is that's the dominant culture generally. A lot of that culture, the "baseline American" culture, is of interest to people who aren't in that group, but the reverse is true way less frequently. Indian-Americans are going to know what Christmas is and might even participate in a gift exchange, but are white people going to observe Diwali? I was the only LGBT person, and THAT experience is way more isolating. Groups around interests are great, but you run the risk of creating groups that are popular/mainstream and still fail to include those who are not as mainstream in their interests. The whole point is to help people who feel like they are different find their place, and a lot of potential interest groups can start to look like a white male club under a different label. For instance, consider a craft beer group, or an (American) Football group.
