1 and 2 seem to mostly be objections to the presentation of the material as opposed to the content. 

Not in the sense that I don't like the font. Lack of justification or point are serious issues.

There are plenty of horrible math books out there; would you use that fact to claim that math itself is flawed?

EDIT I have already said that this isn't about that is right .or wrong.

I can find out what math is from good books. If the Sequences are putting forward original ideas, I have nowhere else to go,. Of course, in many cases, I can't tell whether they are, And the author can't tell me whether his philosophy is new because he doesn't know the old philosophy.
