Most of the 'gray tribe' stuff I remember was them being performatively over-upset with anyone left of Republicans, and mysteriously quiet about Republicans. A whole lot of 'both sides are the same' on drugs and war.

So basically, they were Republican kids from Republican families too embarressed to admit that to themselves or others.

For gay rights, see Log Cabin Republicans, out and proud gay Republicans, so basic acceptance of gay people having a right to exist doesn't make you automatically Blue.
