My supporting POV on selfishness motivating human moral values

[smax]

And was that our federal holiday? No?

First, let me apologize for the delay in response. I don't always have the time I'd like. 

Anyway, you seem to be intent on ignoring the spirit of the holiday while focusing more on how it's come to be accepted by people who have the luxury and preference of ignoring it's implications. There is a reason why Native Americans, in general, do not accept such a luxury as an option. 

I also think you mistake my intent on why this issue was brought to light in the first place. It was merely to show that people always chose what suits their own selfish motivations. Here we have several examples:

• European settlers wanted this land, therefore, killing off Native Americans suited their selfish interest.
  
• Some Native American tribes were at war, therefore, aligning with and using European military superiority to defeat other rival tribes suited their selfish interest. 
  
• Thanksgiving is now thought of as a celebration of peace between European settlers and Native Americans because that perception suits our selfish interest. 
  
• It's original intent, which was the celebration of slaughter, enslavement, conversion, and victory of defeating Native Americans, served a selfish interest during it's time, when eradication was largely the preference of European settlers. 
  

My intent was not to create a debate about the meaning of Thanksgiving, although I admit I chose that example to expose a relevant example of selfish interest dictating morality on multiple levels. I could just as easily have made the case using slavery or the holocaust as an example. 

Anyway, I think the content of this thread, both views for and opposing, have served to support the theory, which did originate with me by the way.
