I've not seen that, but I've only been to a very few Catholic masses. I'll ask my daughter, who is Lutheran, and my son-in-law, who is Catholic, about that. (His mother takes communion during Lutheran services, as does he, and AFAIK, my daughter does likewise at catholic masses)
But, there is still the fact that the women were not merely women, but members of the US Military, in uniform no less. They were actually out of uniform during the time in the Mosque.
I don't want to be overly old school, but for a non-Catholic to take communion at a Catholic Mass is sacrilege. Has to do with the communion being literally the Body of Christ, which is the Catholic and Orthodox belief, but not that of others. Can't speak to the Lutheran position, although my Dad was a non=observant Lutheran. He rarely came to Mass, and NEVER took communion.
