Loyality and Inoffensive to virtue?

Is the inoffensive to faerie or similar virtue affecting the -30 loyality from a normal gift?
At last I would expect that over short or long a covenant where most or all magus have this virtue will mostly have members with Faerie Blood or even Faerie because they are not negative affected by the gift of the magus what should then in return reflected in the loyality modification for this magus.

If all the covenfolk have faerie blood or are somehow aligned with Faerie through supernatural virtues, then inoffensive to faerie would count as the gentle gift for purposes of covenfolk loyalty. If any covenfolk don't, I would still apply a penalty.
