I'm sorry, what persecution exactly?
You mean the temples in the duchies of Madina and Paisly that Mendicant specifically ordered to be left untouched and remain as such save for one temple? Or the priests we allowed into the realm and gave legal immunity to? Aurvandil hasn't persecuted VE, however VE made a point of spitting in our face when they stole land and incited a Dukes rebellion in order to further their religious aims. Don't try to act like they've been persecuted, when at most Margrave Lex refused to let them build a temple in Madina after Margrave Lucius went against Mendicant's order to tear down the temple, which was Lex's right to refuse them as it was his city, to which they responded by stealing an entire duchy and giving to the Grand Duchy and then trying to incite a war against Aurvandil, and failing that, incited one against the Falkirkian Freestate who held the right and claim to the lands they stole.
VE hasn't been persecuted, they just haven't got their own way as much as they'd like. But really, Aurvandil has been overly courteous to a religion we didn't need to be with and had no reason to be.
