Yah I noticed...curious what the explanation is..
It's for the same reason gays redefine words. They take a word (or a phrase) with a known and accepted meaning, redefine it to mean something else that fits their agenda (usually political), that way you are more likely to agree with them.
Cult, baby, infant, child, person, murder, equal marriage, civil rights, normal. It's quite a list.
Some even make up entirely new words and phrases, like homophobia, equal marriage, prenatal infanticide. It's quite a list, too, and mostly banal.
In both cases, it's really little more than a three-year-old screaming and stomping their foot on the floor in the candy aisle at the grocery store because they want to be satisfied by that Snickers really, really bad, therefore they should have it.
