The reason your second experiment failed, where you tried to break your argument down into postulates, is because you changed the audience that would react to it.

In the first case, if you write a moderate-length, articulate, well-reasoned argument, you'll get a certain amount of similarly written responses back along with all of the normal internet chaff.

In the second case, you lose the interest of those with something insightful to say, while simultaneously making it more accessible to people that wouldn't have bothered to write a reasonable reply to the first case. ...Also, your postulates were badly written.
