But then we wouldn't be Ultras :D ... accrding to wikipedia: The four core points of the ultra mentality are:
* never stop singing or chanting during a match, no matter what the result
* never sit down during a match
* attend as many games as possible (home and away), regardless of cost or distance
* loyalty to the stand in which the group is located (also known as the Curva or Kop).
Although I am aware of Ultras who have made silent protests in the past. The wikipedia page on ultras isn't a bad read

I'm personally not sure I'd be able to stay totally quiet without cheering the lads on in some way... it would be easier to not show up at all or walk out if this stuff continues.
