They claim to prize religious tolerance. In countries which hold to the Witchcreed, one can worship any way one wants, but many non-Witchcreed religions are severely strangled by laws preventing their religious rituals to take place.
For an example, if the Witchcreed orders people to pray thrice a day at certain times, then the laws are set up so that organized prayer may only take place during that time (although of course you’re free to pray to anything you like!) and religions which would want to pray at different times are thus persecuted.
Additionally, the Witchcreed is known for sending missionaries to convert other people to Witchcreedism, and then declaring war to protect these new converts from their previous government.
