People who say 'two things, a) blah de blah and secondly....' It's A and B or First and Second!!!

Less instead of Fewer gets me every time and I shout at the TV when an advert that uses it is shown.

'Compares to' instead of' compares with'.

I can accept that we are ruled by Microsoft's version of spelling (even when the thing is set to English rather than American English) but am driven completely spare by books and publications that have both UK and US spellings used with gay abandon, often ON THE SAME PAGE! I dearly wish to go through certain books with a red pen, correcting every mistake and send it back to the author with the exhortation to employ a proofreader or at least a bloody spell checker! The worst offender was a 'vanity printing' tome that professed to be 'one of the best guides' to its subject matter... Opened at random, I gave up counting after the spelling mistakes, grammatical and typesetting errors got to 2 dozen on one double page. Obviously the subject matter was not 'how to write correct English'.

Another pet peeve is the continued publication of historical "facts" that have been proven to be otherwise. The accusations of murder levied against Richard III is a prime example. The account of these murders were written on the orders of the man who had just usurped Richard and wanted to dispose of any potential threats. Tudor 'historians' state that Richard III had his 2 nephews murdered in the Tower of London when in fact, there is no contemporary evidence that this happened. When the Tudor dynasty was exhausted, a retraction was broadcast and Richard exhonorated. However, if you open any school history book published in the last 200 years, you'll see that Richard murdered the Princes in the Tower and that is it.
