As noted at Fox News, a US Army trainee complained of religious discrimination after superiors used remarks denigrating to the Jewish faith and required him to remove his yarmulke.  (As previously noted, some religious attire is authorized in uniform; in fact, the yarmulke is the only such attire specifically mentioned.)

The soldier also was the victim of assault.  According to Fox News, the Army does not believe the events are connected.  Michael Weinstein, however, not only believes they are, but believes that those responsible must be Christians.

[T]hese ever more frequent, tragic matters [are the result] of unbridled, military-sponsored Christian religious oppression…

Like every allegation, Weinstein said he intends to include this in his lawsuit(s).
