You're still wrong on every count that I mentioned.
1) There's no mention of construction workers here, 2) the parade was a memorial day parade that the KKK just went into, your cite doesn't say otherwise, and 3) there's still no evidence that Trump was a member of the KKK there.
Re: #3 - you're citing wikipedia there, and that's a living document. I can submit a change to wiki tomorrow. No archived historical documents name Trump as a kkk member, or at least nothing that you have provided.
Go fish.
