Instead of advice, I'll give you a statement: being offended about something you insufficiently researched makes you look bad.

You are certainly trying hard to make me look bad but regardless of whether you are successful in persuading your audience I reject your claim. I have more than enough evidence to conclude that I would prefer a peace prize that is awarded to Stanislav Petrov and Gandhi than one awarded to Yasser Arafat and Al Gore. Or Barack Obama for that matter. That's like awarding little Johnny US the Encouragement Award because he punched and stole the lunch money of slightly fewer of his classmates this week.

Being offended on the behalf of Gandhi makes little sense- why would he want more conflict because of him?

Is there anything I have ever said or done on lesswrong that gives the impression that I have anything like Ghandi's philosophy for dealing with conflict? Gandhi's tactics are highly situational and work only for those particularly adept at judging and manipulating public opinion and for those who are too helpless to do anything to improve their circumstances. No, my advice for the most practical and ethical way of dealing with oppressors is to not protest at all, not let them know that you oppose them and systematically assassinate all their leaders until they leave.

I further suggest that if you don't think Gandhi's example would be consistent with getting offended by things then you totally missed the point of what he did. The guy did hunger strikes and silly walks to fetch salt as a way to broadcast how offensive things are. He wasn't nice, he just wielded offense and public opinion as his weapons.

and being offended on the behalf of your species makes less sense. The Nobel Prize committee is beholden to Alfred Nobel and none other.

Again, you miss the point. The Nobel Prize committee is beholden to Alfred Nobel. The rest of the world, including myself, are not. The rest of the world are free to make it, as wikipedia puts it, "a highly regarded award, recognised internationally" or to marginalise it as a bad joke by a meaningless institution. We as individuals can then evaluate the aesthetic appeal and expected consequences of the 'Peace' prize awarded as it is. We can also consider how public opinion of the prize as a respected institution reflects on human psychology.
