I know sarcasm can be an effective way of making a point, but on a global forum where plenty of people are likely to not have a clue what unions do or don't exist in Europe (not to mention most Europeans won't know much if anything about unions in European countries other than their own) it's worth not being sarcastic so that your comment can be understood by more than just the people who already know what you're saying.
