In a recent post, moderate blogger Carson T. Clark characterizes a lot of Christian apologetics as follows:
"Generally
 speaking I can’t stand the self-assuredness, snooty condescension, 
intellectual pride, defensive posturing, offensive aggression, 
judgmental tenor, graceless attitude, petty one-upmanship, scriptural 
proof-texting, oversimplistic assertions, binary categorizations, 
rhetorical strategies, academic format, absence an any true personal 
transparency (about doubt, frustration, confusion, etc.), unwillingness 
to acknowledge sound points made by the 'opponent,' refusal to admit 
ignorance (or a sheer lack of expertise) in certain areas, and just 
plain stupid arguments that I’ve typically heard espoused in this field.
 All of which is why I’ve tended to avoid christian apologetics like the
 plague."
Carson goes on to say that a recent talk by Tim Keller 
(which Carson posts) has given him hope about Christian apologetics.  
Whether you have the same positive impression, you can judge for 
yourself.  I watched the video earlier today, and there were things that
 I liked and disliked.  But I loved Carson's characterization of much of
 Christian apologetics.
