It’s not going to be long until they have the entire alphabet co-opted.
yep, considering they began with only “homosexual” rights, then moved to “gay”, then managed (so far) to add in L,B, T and Q. They also created derivative flags for Bisexuality and S & M (which added a heart to the bisexual colors). They may have to add letters for the gay marrieds, for those in civil unions, as well as those looking to adopt or use reproductive technology. I really would not be surprised if the rainbow multiplied as the special rights and protections do.
