This discussion reminds me of the Brass Eye episode about peodophilia which was broadcast and then shot down by numerous do-gooders, 96% of whom had never seen it. Except in this case, I'd suggest that the amount of people ignorantly hypothesising about why Nick was sacked (on both sides of the argument) is far higher than 96%.

But I tell you this, if he was sacked for throwing stones at an immigrant then we should string him up!

But if he was sacked for stopping a BNP man throwing stones at an immigrant, then he should be made a Knight!

All! Or nothing! But in complete ignorance!
