I've found that even if an ERG was created around a particular identity that does not mean that you have to have that identity to be welcome, for instance -- everyone looks forward to when the Indian ERG throws a party because the food is amazing, everyone is invited and the event schedule is public. Also, ERGs are simply a more formal organization, in my company official ERGs some receive funding to support events. At a previous work campus we set up regular basketball and volleyball games after work using a simple mailing list and a share point like internal forum system. I've seen groups where the focus is those who identify as "makers" and also a group for drone hobbyists. You can think of these groups as "special interest groups" to use a political term, but most of these groups are not exclusive.. for instance, you can join the NAACP regardless of race.
