Is it an affectation if you don't notice you're doing it?

This would be a sort of IFIAYAQD! sort of thing but it's Tuesday and I just can't justify it.

This morning I was writing an email to a friend about job advice. And at the end, I glanced back at it and--
You've probably seen me do this before. I had started celebrating language again. Baroque sentence structure. Words you can't even find in the New York Times any more, maybe in an Austen novel. You know how I do, you've been riding dirty with me before. It was fun to read, and it had been fun to write once I thought about it. I had more than one person remark about this phenomenon in the last story I finished.

This friend is wikkid smart and I'm pretty sure I'm not talking over his head. I *hope* I'm not making him work too hard to read it, because I'm asking for his frickin' help.

The actual question part: Does writing like that in a situation that does not require it (eg a Wodehouse short story or something) make me a pretentious git?

Things that make you go Hmmmm

So the NRA has decided they don't want functional guns at their convention, despite the danger of an outlaw bad guy having a gun and shooting the place up.

So the NRA maintains records of their members, thus effectively making a list of people who own guns and are more likely to be politically active about it.

Hmmmmm

EDIT: functional firearms are forbidden on the arena floor where big events are taking place, outside of that only the dealers are required to neuter their guns.
However, they are still collecting names and making a list of known firearm users.
