Yes, I've drunk the koolaid and really think that it's likely that there has been some harassment. I'm not fixated on the racial slurring, I think that it's likely that he learned to ignore it a long time ago - it is the tip of a sh*t iceberg. Richie has a background of being unable to control certain behavior especially when drunk (possible sociopath, but also clearly loved by many teammates). I also don't think that Martin is just driven by the motive of making money. Call me naive and feel free to chargrill me, but what I see is a smart young guy, who had always done well at everything until entering the NFL and was struggling to make it in his chosen vocation. He has been raised in a very affluent family, had the best education and it appears that he suffers from depression (and Incognito's father has alluded to suicidal tendencies on this website). He simply flipped out in an emotional display that probably disgusts him, but that doesn't make him crazy or simply a money digger. My read is that he is driven by personal achievement and the prospect of a big payout is just a backup scenario. I think that he probably enjoys playing the game and wants to do it well. Note, depression can be successfully treated with medication, but it can be tricky getting the right medication and dosage.
I thought that it was interesting to hear Incognito's former Nebraska kicker answer in a radio interview. As soon as he heard of Martin walking out re harassment, his immediate thought was Richie has finally gone too far.
