I have read the exchange of posts, and also the original blog argument.
In my opinion AdminModulus was too generous. Your argument is inadequately developed and as it stands does not constitute a valid challenge to accepted ideas. More work is required before I would consider it for promotion.
There is no rule against quoting - only a rule about relying on quotes to make your argument (rather than providing supporting evidence).
Since the problem is that your argument has not been adequately made, further quotes would not address the issue. And in fact the blog entry does not provide support for your argument - indeed it raises difficulties which it would be good to address in your OP.
In the light of the information given in the blog post, I would like you to show that your points 2 and 3 have any relevance. At present you have offered no reason to think that they have. Testability is important but it does not impact the plausibility of the explanation, thus your point 4 is moot. And your first point - the only one left - is not sufficient as it stands to carry your argument.
This is not the place to discuss the relevance. The point is that you need to include such an explanation in your OP. (I will warn you - in the hope that you will improve your OP - that you are ignoring information in your source which seriously undercuts the simplistic argument that you raise).
