ser demasiado quisquilloso

(v.) = put + too fine a point on, split + hairs

Ex. Not to put too fine a point on this, and slap me down if I am being rude, but from the questions you are asking I do not think you are ready for a project of this scope.

Ex. This volume is too long, contains too many lengthy theoretical arguments that often split hairs, and is written in a tedious prose style.
