Did you really though? Because it's very clearly not a serious apology. Perhaps people being so gullibleas to not recognise someone being insincere when it's staring them in the face is why Clarkson has so many defenders left.
He prefaces the apology by complaining that apologies are never enough these days. Then he puts in the childish "from the balls of my feet to the follicles on my head" line just to really hammer home that this is not a serious piece of writing.
Other than that, he is still refusing to accept that his expression of pure loathing for someone he's never met was weird or wrong, and is still hiding behind the fact he was drawing from a scene in Game of Thrones as if that changes what it is that he's saying should happen.
If someone said they wanted to curb stomp Jeremy Clarkson like in American History X, or Meghan Markle should reenact the sodomy scene in Girl with the dragon Tattoo and tatto his offences on his forehead...they're still saying they'd like those things to happen.
So he's failed to even take responsibility for his comments, and he's ignored the fact people dug up lots of similar comments in previous articles about Markle. So much for "a mea culpa with bells on".
I think the fact he wrote an apology to Prince Harry, not to Meghan Markle sums up just how cowardly he is, and the fact he couldn't wait a month before publicising this "private" apology shows the motivations behind it.
Oh and ending it with "So can I move on now?" is absolutely pathetic.
