"Protestant" isn't even close to the right term ... to describe what OP is getting at. Using that term immediately discredits any point he's trying to make.
And it all depends on what OP considers "petty stuff". Some people consider dogma and doctrine to be "petty stuff". Hey, why fight about it? Other people might consider arguing about the Tridentine Mass vs. the Novus Ordo to be "petty stuff".
Perhaps OP is lax, and perhaps there's some merit to what OP is saying. But we can't even begin to evaluate the merits of his claims unless he gives some specifics.
For OP, I'm guessing that complaining about things like women wearing pants on that one SSPX picture is trantamount to "moaning and groaning about petty stuff".
So, unless OP provides and substantiates concrete examples of "petty stuff", we can safely write off OP's complaints as a reflection of himself being excessively lax.
