@gavo in some cultures there's a tradition where young girls get their clitoris cut off, just because, according to their tradition, women can't feel sexual pleasure, or something.
Would this be acceptable too to you?
Accepting our cultural differences is cool, but using culture as an excuse to be a retarded dick isn't.
Bullfighting traces its roots to prehistoric bull worship and sacrifice. The killing of the sacred bull (tauroctony) is the essential central iconic act of Mithras, which was commemorated in the mithraeum wherever Roman soldiers were stationed. The oldest representation of what seems to be a man facing a bull is on the celtiberian tombstone from Clunia and the cave painting "El toro de hachos", both found in Spain.
For fucks sake, are you serious, Gavo?
Come on dude, that's totally different. The racing horses die by accident and people go to the races to see those beautiful animals run. On the bullfights the bull dies for people to have fun and people go there to see the bull being pierced by a sword dozens of times.
