Respect for flags and other national symbols

So, I am currently attending a big scouting event in Europe and there are people from over 50 different countries. And I have noticed, that quite a lot of them are acting (at least for me) in a very disrespectful manner towards the flag. Starting with the smaller thinngs, most people have flag tied on a rope between their tents (the flag is tied in top left and top right corners). In my opinion, it should only be tied on the left side, while the right is hanging freely. But I can kind of understand that, because the flag is much more visible, it's easier and nicer to do it this way. However, it gets worse. Earlier today, when it started drizzling, I saw some people using their flag as head protection. And, in my opinion the biggest sign of disrespect, when we had the opening ceremony, there were people laying their flag on the ground and sitting on it, not caring who steps on it or anything.

What are your thoughts on this topic? Is this just me overreacting? Or do you think this is a serious problem?
