I'm torn on this kind of thing.
One part of me says "f@#k the man; they should leave people like Jon alone!"
Then there's the other, business-owner, part of me that says "If I have to have a business license, pay taxes, and deal with all of the other governmental horseshit that comes with it, why shouldn't these "professional" flipper guys have to as well?"
(There's no judgement or anything intended on my part, and in the end, I hope they leave Jon alone. I'm just sharing my feelings with the group.)
