I will just express my feeling after watching the Pamplona bulls run, without understanding anymore the issue.
I am against,................ I am against and I do not believe that this kind of popular tradition (running in front of bulls without any sense hoping not to be hit or overrun by the bulls) is still representing anything linked to San Fermin week festivity, which should be a religious momentum, improperly called Festival.
San Fermin was a catholic martyr (in 257 AD), allegedly by being tied to a bull by his feet and dragged to his death, but should be also a legend and maybe he was a relevant catholic priest beheaded without been involved in any bull dragging.
Anyhow, I do think that bulls should not be involved anymore in a religious festival, where the main point is no more religious celebration about a saint, but just a touristic attraction for over 1 million spectators and every year people get hurt and bulls are obliged to run without any target just for touristic environment and fun.
I guess that the brave people searching adrenalin in front of a bull, forced to run without any sense, could find today a better issue like adrenalin park, natural glass bridge, climbing skyscraper or just substitute the real bulls with robot bulls (but do not enter too much complicate software in AI bulls otherwise somebody will get hurt as today s with the real bulls)
So just leave the bulls in peace and San Fermin will still be a great saint of the Catholic religion.
