While you may not prefer to label White Supremacists rabid, they are certainly far right fringe extremists and they unanimously supported Trump based on campaign rhetoric. I really don't believe that these fanatical organizations will be happy with anything less than what they heard promised during the campaign. If you don't believe that then I suggest you check their websites.
I'm not sure I understand what you think they heard that would make them so happy?
Deporting illegal immigrants possibly but Trump never said he would deport any one race of people despite what his detractors said about his immigration policy.
For example, what Trump said about Mexicans:
"When Mexico sends its people, they're not sending their best. They're not sending you. They're not sending you. They're sending people that have lots of problems, and they're bringing those problems with us. They're bringing drugs. They're bringing crime. They're rapists. And some, I assume, are good people."
And of course he is right. Mexico is not sending their best and brightest and in many cases criminals. Poor and cheap labor represents the vast majoirity of illegal immigrants coming across the border. Illegal immigrants make up 3.5% of the population yet they represented 36% of all federal criminal convictions in 2014 so there is absolutely a connection between illegal immigrants and crime.

What he did not say was that all Mexicans are criminals like many in the media reported. The far left in this country has demonstrated an inability to distinguish between legal and illegal immigrants.
Even on banning Muslims he never said he would deport all Muslims either but he did say in light of the inability to vet the people coming here from the middle east that immigration should be halted until that vetting process can be solidified. Once again I'm not seeing the racial animosity since Islam is not a race.
Remember that the brothers of the Boston marathon bombing were immigrants. Obviously our vetting process failed there as well and considering our own government admits our vetting process isn't working why would be blindly allow people in here without knowing their background or if they even agree with our government philosophy of freedom for women, homosexuals and representation?
So again I'm not seeing why white supremacists would be so happy any more than black supremacists who support the BLM movement that Hillary endorsed would be happy with her.
