Your "advice" was that I need to prove I can do something before doing something, which is literally impossible.

No, its not impossible at all. How do you think I got in the position to do the things I do? Not wanting to put work in doesnt make things impossible.

A rational response would be to listen to my plan, ask thoughtful questions, and if you found it stacked up, give it your support and if it fdoesn't point out what is wrong.

I gave you a rational response. Show the community you can do any of the things you claim and people will take you seriously.

"I am trying to build consensus and support for the plan, so if I could gain that from you, it would be awesome.

I told you that is not how you build a consensus. I dont know you. I dont know what you can do. Youre not active on Hive and havent shown youre capable of anything, let alone the big things you claim.

In summary, you refused to listen, leapt to conclusions, and blew me off without ever taking the trouble to find out if my plan had any merit at all.

I listened to you plenty and explained everything in detail. I explained it to you again here. Hive is a reputation based community. Thats why we have no rugs here. You have no reputation and are clearly unwilling to generate any.
The first step is understanding Hive. Understanding decentralization. Being part of discussions. I guess this here what youre doing is a good step in that direction.

I had to look up disingenuous and it equates to deception, so again you have just made stuff up,

Being given an honest and helpful answer and then painting that as us Hivers (news flash, youre a hiver too) not being open and welcoming is disingenuous.

approach rather than making stuff up

Again. Disingenuous.
