I don't know why she said 70 mosques, she obviously knows there are more, 162 in Birmingham alone and at least 1,750 registered mosques in the UK, must have been a slip of the tongue.
Re. the word decimate;
Does ‘decimate’ mean ‘destroy one tenth’?
Most people have a linguistic pet peeve or two, a useful complaint about language that they can sound off about to show other people that they know how to wield the English language. Most of these peeves tend to be rather irrational, a quality which should in no way diminish the enjoyment of the complainer. A classic example of this is the word decimate.
The complaint about the word typically centers on the fact that decimate is used improperly to refer to ‘destroying a large portion of something’, when the ‘true’ meaning of the word is ‘to put to death (or punish) one of every ten’.
There are several problems with this complaint. The first, and most obvious, is that language has an ineluctable desire to change, and there are almost no words in English which have been around for more than a few hundred years without taking on new meanings, changing their old ones, or coming to simultaneously mean one thing and the opposite (a type of word known as a contronym).
