I'm interested that you think the following doesn't really have a 'tone':
I'm also interested to learn what, in that post, gives me (or anybody else) grounds to believe you understood it.
Interesting, finally, that you think 'laughable' isn't patronising, but me giving my view that you'd missed the point is. Noting that my assumption you'd missed the point was, at heart, giving you the benefit of the doubt. The only other interpretation I've been able to come up with was that you were unable or unwilling* to express disagreement with the post by taking issue with its content, and could only resort to insult.
I think it's telling that you invariably think the fault always lies elsewhere than with you. And any of us who beg to differ are 'the usual suspects'.
*this has been common in your responses. Carp, but almost never engage critically.
