I don't get the righteous anger. The memes don't say "I fast", "I pray", "I attend services," "I try to follow the canons to the best of my ability". They say "I fast, but judge", "I attend services, but don't understand what they're for," "I judge those who don't follow the canons I adhere to, but dismiss the canons that don't suit me." If people don't find them funny, that's understandable - it's geeky humour - but the vast majority of the memes are definitely not a mockery of traditional piety and as such should be fairly ignorable, even for the most demanding inquisitor.
