there's no internet tough guy image; i correct grammar and spelling outside of here as much as i do in here. it's simply a pet peeve of mine.
yes, i realize that i am saying this while typing in entire lowercase, too. i understand the irony.
if you have a legitimate beef with me correcting your grammar now, after what; five years? then something's been brewing and it's not something i can really help, and i can only offer my condolences to you for bottling it up as long as you have.
otherwise, don't falsely attribute obsessive-compulsive where it doesn't exist.
