Mark419ny, first of all let me start by saying that was one of the most reasonable and well articulated posts I read from you.
Although I don't agree with some of your points, you explained your point of view clearly and in a thoughtful way.
I just think that's time to move on and judge today's actions alone and in their own merit. Even Race Direction as done so, by telling everyone that from now on the sanctions and penalties will be harder. (If they have succeded with this new system is clearly open to debate due to some questionable penalties that have or not been handed out (the name Aaron Canet comes to mind)).
If you are always stuck in the past and in what penalties or lack there of have been imposed in the past, the sport and the job of RD will never improve.
That's like telling the officer that just handed you a ticket for speeding that 5 minutes ago another rider passed you way faster than you were going and he did nothing. I bet you would be ticketed anyway.
Moving on to your questions, and I'll reply without glasses of any colour, shape or form and trying to answer without any bias (as I said, I admire both riders equally for their talents and I can also judge them for their faults):
1. I agree. If it were Marquez instead of Dani, I think a lot more ink would be put on paper.
I don't see how Dani could be blamed for that crash and I don't buy the argument that he is behind, so he is the one that can see what's happening in front of him and anticipate the future.
So, if it were Marquez doing exactly the same at the same place, I wouldn't put any blame on him either but I definitely think that there would be some kind of uproar.
However, when you say "they have to keep it close", I'm not sure to whom you are referring to (the powers that be, Dorna? the media?).
I don't think that that uprar would be due to some plot against Marquez. It would be due to the fact that he is one of the most relevant riders right now and the one that's constantly at the front and under the spotlight.
2. I disagree. Marquez didn't have the line, he came in too hot, there was no room for him to put the bike there. If you check the different angles, including the one from the helicopter, that wasn't the typical block pass where a rider opens the door and the other one takes advantage and forces him to pick up the bike.
There was no room, Rossi was already commited to the apex and Marquez barged through the corner. Even himself acknowledged the severity of his pass since he promptly apologized with his hand.
After the race he recanted and said something about hitting a wet patch (that you can see that wasn't there), but that was just PR.
So to answer your question, in that situation if Rossi and Marquez had reversed their roles, I would blame Rossi just like I blame Marquez and I believe that Rossi would have been penalized.
In 2015 before Sepang, maybe you're right, Rossi wouldn't be penalized for that pass alone. But if you count all the actions and paint swap with other riders of Marquez since the start of the race, then I think if it were Rossi, he would be penalized, be it 2004, 2015 or 2018.
3. As I said above, Marquez didn't have the line and that's easier to see by checking different angles. Nevertheless, it's my opinion Rossi should have been black flagged in Sepang. and then he would have started Valencia according to his qualifying position.
As I said, I was disappointed with Rossi in Sepang since the pre-race press conference. I don't think there was any plot between Marc and Lorenzo against Rossi. Even though I don't believe he kicked Marquez, his actions were inexcusable. He waited for Marquez and ran him to the edge of the track.
Sure they don't like the guy, but nothing more than that. And I even think Marc trully admired Rossi since an early age as he said.
But to answer your, why wasn't Rossi penalized in Sepang? He was, he got penalty points add up to his "account", which together with the penalty point he got earlier in the season, granted him a start from the back of the grid in Valencia.
Was that enough or the right decision? IMO, definitely not as I said above.
