I cannot believe us grownups are concerned about such nonsense. This is political season and one can read anything into any of these ads. Check them all out and then let your imagination go to work. Every ad has intended and unintended messages - so be it.
I don't know if you remember -- I think it was in the 70s -- that when the Post Office put out a Christmas stamp showing a candle (maybe a wreath -- it's been a long time!) in a window with those dividers that look like a cross, there was enough of a ruckus about the "cross" that they withdrew it?
