I try to be a bit more tolerant in the "Beginners & Help" and "Bitcoin Discussion" sub-forums. Those are filled with newbies that just want to talk about bitcoin related stuff. I have no expectation that they have any particular level of knowledge about any technical details.
Just chill out man, no need to be rude.
If my idea is worthless, then it strengthens the point why ECDSA is needed, and people will apreciate ECDSA more.
If my idea has some worth then it could give ideas for developers to create a system like I described, perhaps as a side-chain.
Either case, it is worth discussing this in my opinion, discussing things is never wrong, no matter what is the outcome, people will come out as winners because knowledge will be shared.
