Can anyone translate this for me please?

I would have resorted to Google Translate, except the last time I used Google Translate, I got this:
 

Lesson learned:  Don't use Google Translate.

One way to use Google translate is to carry out an (admittedly rudimentary) accuracy check, as follows:
Take the resulting translation and have Google Translate translate it back into English. 
Does it make sense when translated back? This gives you an idea of the accuracy.

Once I needed to rebut Palestinian Arab propaganda into an answer that needed to be in French. 
By carrying out the above form of checking I could see that the translation as it stood did not make sense. I kept changing the original English wording so that after a few attempts, when the French translation was translated back into English, it made sense. 

I never got criticism from French readers of the translated text when I carried out that form of checking, but I did get criticism from the French readers if I did not carry out that checking!
