How do apologists defend against Bart Ehrman's arguments that Church scribes corrected and changed the Bible to fit their theology?

Bart Ehrman seems to be the atomic bomb of the Christian community, having released books like *Misquoting Jesus* and *Jesus Interrupted*, which call into question the reliability and inerrancy of the Scriptures, particularly the New Testament. Are his arguments new? How does one respond to or refute his arguments? For example, Ehrman argues that some scribes "corrected" or reworded certain verses to fit their particular theological views or to align with what made sense to them (e.g., Jesus being angry as He healed the leper).
