Refer to the first sentence too, not just the second. There are two points that compliment one another. On the one hand, them being open shows just how much of a leech Hollywood (capitalism wretchified) is, and how anti-Christian it is... on the other, that families go to see films on Christmas Day show how Christian they are; Hollywood's narrative and economic tendencies are very Christian - though if it were that Christian, staff would have a day off on this so-called "national holiday".

Like I said, money talks.
