What I have come to understand in 3 years of posting here is that 

1).  Many, many posters here are NOT Catholic.  They are members of other faith traditions or people who have left the Faith for whatever reason.  They seem to have a desire to belittle and dismiss those of us who are Catholic.

2).  There are those who are CINO - and would like to have the Church bend and change to their will and set of beliefs.

3).  There are those who appear to simply want to destroy the Church.
