T-Man, I hate to revert you, especially given that we are apparently going to arbitration and all, but your addition is contrary to the consensus that tooks many weeks to build on this area, and which you left alone until now.  You still seem to be trying to prove that Batman is not gay... we all know this.  Here is your addition:
 However, quotes from the creators of the characters would be missing yet, and Batman had previous romantic interests prior to this point 
Firstly, the comment is not too encyclopedic.  Secondly, no one said that there are quotes from the creators; what was said was that "it has been suggested that" the creators did this in response to the Wertham allegations. This is logical to conclude.  As well, your web citation is not very useful in addressing this issue, although it does seem useful to show the dates the various characters were first introduced, and can be put into Batgirl and other sites (in fact, is already there).
I am going to be very civil with you from now on.  But that doesn't mean I don't have great concerns about these edits, particularly when they address the same issue month anfter month with no flexibility.
