So, if you don't like the counter, just don't download it.You cannot count on people behaving this way, least of all when it comes to politics.
There must be a way to stop this rejection-crazyness.
Broad rejection under the banner of "politically charged" is probably the most sane solution for Apple. The more they permit, the greater the backlash over any particular rejection, and the more their permission would be construed as endorsement.
For instance, suppose a pro-life and pro-choice application are both approved for the store, but one (it doesn't matter which) is only approved with a higher age limitation than the other due to content. Even if Apple's rating approval were completely consistent with other applications, the discrepancy between these two is practically guaranteed to cause a shitstorm. Multiply that by every other axis of approval or rejection and every other political issue in every country Apple runs a store.
