Nah. I see a lot of sugar coating here. Net positive and being welcoming and humble is always better than being even 20% dick. Over the top proclaiming things like "You don't know what you are talking about you n00b, THIS THE WAY. Accept it or get out" is far more damaging than saying, "You know what, yeah you do got a point, and we should explore it more, but here's why I have strong opinions on xyz". No one knows everything remember and can't know everything, so how about show some humility and be welcoming. I hope you take this is as positive criticism Darth.
