When does tradition stop making sense?

When does tradition stop making sense? 

One of our editors at Italy Magazine, Katia, posted an article about two horses being put down after their traditional 'giostra' race in Pistoia. This subject that we personally find compelling and is one that brings about many opinions. The main question is, are these traditional races outdated and should be do more to protect the horses  or is this just part of life in Italy, these traditions are sacred and shouldn't be altered? We want to ask you guys, our awesome Italy Magazine community, what you think about this subject (I linked to the original article above).
