Please don't be a pedantic nitpicker, it lowers the general level of the discussion (I realize the irony in this very comment doing the same). It's quite obvious that he meant 'compatriot' as 'co-conspirator' or something in that vein, not as in 'everybody who happens to live in the same country'. And even if he did, he'd be such an extremist that you wouldn't be able to reason with him anyway; in which case just ignoring that part would be best.
