Say wha?

The war on Christmas is very, very real, and if you ask me, in addition to some grouchy misanthropic heathen atheists it has to do - at the root of it - with two things - abortion and the gay rights agenda, because Christianity is against those things. It’s subtle but that’s why it’s so pronounced in recent years.

OK, but how do abortion and gay rights actually, you know, relate to the war on Christmas? Also how can something be both subtle and pronounced at the same time, aren’t those words antonyms of each other?
