Is this hypocritical?

Gf and I got into a discussion a blog she read stated that coloring in mandalas is bad because it can make you more susceptible to evil spirits however he states that coloring in Christian symbols is OK she says this is hypocritical I disagree if he had stated that coloring in religious symbols is bad while he colored one in that would be hypocritical but because he added coloring in this specific one is wrong while he colors in a different one that changes it like saying driving a car is bad while I drive a car hypocritical if I say driving a Ford is bad while I drive a Dodge not hypocritical I m not gonna show her this answer I just want it for my own sake
