No. I read multiple languages. Maybe my friend wants me to explain something in the docs they are reading - should I need to change my browser language to check it for him? I want to look something up from a university computer where I am studying in France - I can never see the docs in my native language from a public computer? I want to look something up on my friends laptop - it has to be in his preferred language? It is nice to try and help a user, but you should always let them override your language decision.
