Reading through the first page of comments, one thought come to mind.
Somebody deliberately blurred the specific MAGA logo on those hats since there was no similar blurring on any other photos that was a political act. It is possible the editor honestly didn't catch it. Unlikely. But possible. Apparently there was nothing in the policy that stated nobody could make a non combative patriotic statement with their clothing. In this case, there was reasonable cause to point out unwarranted censorship and object to it. It does not warrant becoming front page national news.
But one thing is for sure. If those boys had been wearing "I'm with her" or "Obama" tee shirts or hats
and somebody erased the images from those photos, the same folks shrugging off erasing MAGA from the hates would be screaming FOUL to the rooftops.
