Im surprised your not voting for yourself on grounds of piety. That and I don't think any space marine chapters are that petty. Even the Dark angels and space wolves will work together and make decisions for the best outcome for the Imperium. At least until the fighting is done

Compared to how some SM chapters interact this is not that bad. The Minotaurs and the Space Wolves or Salamanders are a good example.
