I feel like that's a rhetorical question considering that his first post in the game was to attack me, and now he's just been trying to justify why he had to do it.
The IRS is providing me with an opportunity to hone my skills, apparently by giving me a chance to kill them all, instead of hiring me out or anything like that.
Well, maybe you got luckier with your flavor text then in what your relation to the IRS then, but generally you're aligned with the named faction in your PM.
It's only fair that you wouldn't have scum doc access until the game started, and if you wonder why someone would be confused about alignments based on their Role PMs, you should probably reference your own role PM and note the obvious.
