The point isn't to agree with the stuff, but to be familiar with it

nyan_sandwich said that the Sequences contain not merely arguments, but knowledge. This implies a rather high level of agreement with the material.

The point isn't to agree with the stuff, but to be familiar with it, with standard arguments that the Sequences establish.

I agree, but:

If you tried to talk advanced mathematics/philosophy/whatever with people, and didn't know the necessary math/philosophy/whatever, people would tell you some equivalent of "read the sequences".

I am perfectly fine with that, as long as they don't just say, "read all of the Sequences and then report back when you're ready", but rather, "your arguments have already been discussed in depth in the following sequence: $url". The first sentence merely dismisses the reader; the second one provides useful material.
