Being brought up as a Jehovah's Witness means you are so used to the term that you rarely stop to think about it.
One thing I've noticed is that people unfamiliar with the religion will say "Jehovah Witness" (no 's) instead which I always found a bit grating.
But watching the US election, something struck me. People are often referred to as "Trump Supporters", not "Trump's Supporters" and so on. Thinking about other things, people would say they were "United Fan's", not "United's Fans" and so on.
It seems weird that a group would refer to themselves as though it was someone else talking about them (in the 3rd person, if I have that right).
What do you think? Does "Jehovah Witness" grate on you too or does it make more sense?
