Neither is pedantry a sign of intelligence, a message many a contributor to this here site would be good to take to heart. As to the choice of language English is and will most likely remain the lingua franca (pun intended) in most of Europe as it is the language which is most often learned as a second language. While many Europeans are not fluent in this language they do manage to read and make themselves understood in it. This makes it not a bad starting point just like the grandparent stated.
