I have no problem accepting criticism.
Honestly, I didn't get the impression that you accept any criticism. The only difference is that some users like Vod or DireWolfM14, insisted on further discussion with you, which eventually escalated into an argument. You certainly did not try to make the whole discussion constructive, but you concentrated exclusively on defending the project and the offer you presented. There is no 100% ideally planned project in the draft phase, and you presented it so persistently.
I don't want to restart or discuss this whole thing, I'm just stating my conclusion that you had too rigid an attitude.
