No, Rasmus did not intend to injure, but his left foot, complete with spikes, was definitely up. And your last point is what matters - if you can't break it up, why the hell are you trying to interfere? Why not, like all other brands of baseball, respect the well being of your opponent and slide into the base? The only thing take out slides ever accomplished was terrorizing the interaction to such a degree that baseball started letting infielders stand a foot off the bag they were supposed to be touching and still called it an out. Now we are take out sliding several feet from bases to "get" the infielder. Because the point of these slides is to take out fielders, something we strictly disallow in every other facet of the game. You know how that silliness stops? Slide into the freaking base like you find when were 17 and not trying to be a kamikaze.
