I can't help but wonder if the ones who decry the previous presenters, are somewhat a little like the Atheists, who not satisfied with being non believers, also find that they need to positively hate God.
When the phrase stops hitting the bullseye another will surface. I always liked Matt Breunig's Purity Leftism. It was just a little ahead of it's time.
I stopped watching Top Gear when Raymond Baxter left.
Might actually watch it again now, once or twice. The Clarkson/May/Hammond triumvirate of puerile, self-conscious "Oooh we can be so un-PC" stuff didn't do it for me.
