Multiple Title IX exempt group membership.

[naraht]

For members of the NIC, NPC and NPHC (all of which are Title IX exempt) are there other Title IX exempt groups that you would feel comfortable with a member of your group also belonging to?

The only examples I can think of might be Phi Mu Alpha Sinfonia (for men) and Sigma Alpha Iota (for women). Are there others?

Are there other pairs of organizations that fit this other than (possibly) Y and Sinfonia or Z and SAI?

This is as a general practice, not exclusive to the letter of the rules. Omega Psi Phi is not an NIC member, and as such I *guess* you could legally have someone who is a brother of both Omega Psi Phi and Sigma Nu.

I'm also excluding Honorary memberships here, so President Trump receiving honorary membership in both ZBT and AEPi isn't an example here.
