The use of religious and/or political statement in miniature painting as a good or ill thing is dependant really on what an individual considers that work to be. If one thinks of it as art, such as with high end display pieces, then such statements, if properly handled, can often be apt. If you\'re merely slapping a few symbols on a squad for gaming because it\'s \"kEwL\" then there is no statement to be had, and the entire impression this gives rides on the merits (or unsavory nature) of the symbol itself.
Where the lines are between beauty, vulgarity, art, and satire (or simply: painted toy) is a matter of semantics. I\'ve always found such arguments a bit silly because of the broadness of the definitions. These lines are always drawn based on individual preference, whether learned or reactionary. No absolutes exist.
For example, a display piece consisting of GW Imperial Guardsmen painted in historically accurate World War II colours and arranged in a trench warfare diorama can be as powerful as any museum quality work. The main difference is the models\' intended purpose as gaming pieces (and therefore would have inaccuracies in equipment, and so forth) but the potency of the message could still be impressive.
On the other hand, a group of Space Marines with confederate flags on their shoulder pads and Budweisers in their hands is something I\'d find pointless and tasteless regardless of the quality of the work. It has no merit in its own right and no message; it\'s solely done to elicit responses based on the symbols alone.
However, I do believe it\'s possible to incorporate either religious or political statements and elements successfully within a miniature work. Certainly the majority of such attempts fall short, and it\'s debatable if anyone has actually succeeded in doing so thus far with the gaming ranges of miniatures, but I don\'t believe it\'s out of place for folks to attempt it if that\'s what floats their boat. After all, it\'s quite common to have such displays at museums -- albeit they\'re not Games Workshop, Reaper, Confrontation, etc productions, but using miniatures is practically the status quo. Moving into the more accessible pewter seems a natural extension.
Eh, but I\'m really waxing on this far longer than I intended. Just in one of my philosophical/analytical moods.
Personally, I avoid patriotic colours on my miniatures. It\'s like using greens and reds can result in an unwanted, unintended Christmas-y feel to a figure if you\'re not careful (yeah, those Khorne guys are ALL ABOUT Santa). When I start drifting towards patriotic colour combinations, I have the same need to rework the figure toward alternate shades. It\'s unlikely I\'d ever feel the urge to paint a specifically patriotic miniature for its own sake.
