That's a bit harsh. I think you're assuming a person can be that brain-dead and still comment on the internet; which ignores more likely alternatives like "he's a paid shill"--seriously, ever notice how the trolls get quiet when certain laws reach their crux time?
It's possible he's here to do a job, to attempt to disrupt this hub of subversive activity, while simultaneously paying attention to what's being said.
Now, a lurker could observe and report, but if you want to disrupt a group you *must* be vocal and ludicrous.
See how we waste our time responding to his nonsense?
And every time a troll fades away, another steps in and fills the exact same function, almost as though somebody hired a replacement. Their number here is constant--the logical conclusion: paid shill.
M: I came here for a good argument.
A: No you didn't; no, you came here for an argument.
M: An argument isn't just contradiction.
A: It can be.
M: No it can't. An argument is a connected series of statements intended to establish a proposition.
A: No it isn't.
M: Yes it is! It's not just contradiction.
A: Look, if I argue with you, I must take up a contrary position.
M: Yes, but that's not just saying 'No it isn't.'
A: Yes it is!
M: No it isn't!
A: Yes it is!
M: Argument is an intellectual process. Contradiction is just the automatic gainsaying of any statement the other person makes.
