Well yes. The EU leaders aren't mythical, omniscient figures, they are human men and women, who don't necessarily have an intimate knowledge of everything, including the internal politics of a country that isn't their own. Just as I wouldn't necessarily expect UK leaders to necessarily know the ins and outs of Irish, German, Italian or Hungarian politics or geography and I wouldn't consider it some great slight if someone were to say so.
Of course, you are so quick to believe the absolute worst about anything to do with the UK ( like seriously believing the MHRA was full of chancers who make their decisions based on politics based on a clearly sarcastic remark I made about how people on here think things work there) and the opposite for anything that isn't the UK that you jump on anything that doesn't fit your own views. Such as a post which is 99% talking about how Johnson is a total buffoon and how his own party's rhetoric and approach have removed the possibility of any goodwill from the EU on this issue (and rightly so) and picking up on a passing comment about how some leaders (including one who called a vaccine quasi effective) may not totally get every intricacy of a political system of another country.
Let me put it this way. If I were to write 'The intricacies of France may well be lost on Johnson/May/Cameron/Blair/Brown/Thatcher/insert whichever leader you like', how would you feel about that statement?
