The Heresy of Orthodoxy, ch. 8

This chapter takes up the most significant questions of manuscript reliability. The authors take the following approach:

• We have good reason to think the original text is preserved in the overall textual tradition.
• The vast majority of scribal changes are minor and insignificant.
• Of the small portion of variations that are significant, our text-critical methodology can determine, with a reasonable degree of certainty which is the original text.
• The remaining number of truly unresolved variants is very few and not material to the story/teaching of the NT.

In order to make a case against the manuscripts, you have to point to changes which assumes an original. It seems like Ehrman's arguments are self-defeating. What is more, Ehrman's problem with the manuscripts is less about evidence and more a theological expectation of a God who would not allow even a single variance. This is altogether unreasonable.
