You're right - I'd guess "proving" (lol) he isn't legally obliged to have an EA license (I doubt he is literally under 13) is his outsider/anarchist party-piece, probably polished by years of practice. He proves nothing, except that he's lucky he hasn't been done yet - a bit like the person who claims they will live for ever on the basis that they haven't died yet.
It's entertaining to watch for a while, but degenerates into farce.
If I felt similarly oppressed by the criminal conspiracy of the state ( lol) I'd be tempted to prove I'm no slave or parasite, put my money where my mouth is and get my caravan towed to one of those places where there is no state - Somalia, Transdniestria, Yemen -and I could be free.
I think "ignore" is the way forward - it has got like being on a train where someone drunk or deranged is talking to you about a conspiracy , or things only they can see.
I only read Sam Vimes' post after posting the above, and I think I'll ignore the member's posts and refrain from adding any of my own to any thread. Sort it out, please, FM
