It's still not a religion.It's an abiding faith in the denunciation of other faiths if we go by the conduct of a majority of it's members of late. I would submit they are as rabidly zealous going about it as Cardinal Ximinez and the Spanish Inquisition also. Ergo, if they are morally repulsed by the sight of another faith, espousing intolerance characteristic of Christian, and Muslim faiths, they must also from a logic driven standpoint be a faith themselves. A faith that knows that if they are labeled as such, they lose the current unfair advantage they enjoy in litigation.
Expect a challenge to it to come in the coming years if it has not come yet.
