I'm simply looking for intellectual consistency. I tend to hold the opinion that politicians aren't necessarily responsible for their more extreme fringe supporters. But having members of a candidate's staff calling for violence against the opposition is problematic. If nothing else it speaks to Bernie's lack of awareness of the people he's hiring.
If Trump had actual white nationalists or KKK members working for his reelection campaign then every mainstream media outlet would be calling for his resignation. But according to you, they are an organized group, so there is a difference somehow. I don't agree.
At the risk of legitimizing your original question from the other thread, I will try and answer it directly. White nationalists and KKK members, as few in number as they are, likely support Trump because he doesn't advocate for open borders and un checked illegal immigration. Even though Trump has repeatedly denounced their racist views, his policy positions are more closely aligned with their beliefs than those of Democrat candidates. Of course, that in no way means that Trump holds the same abhorrent views they do, only that they are more directly opposed to policies of the Democrats.
