Well, for some women it is "reason enough."  And isn't just women who want to be priests who are put off by the fact that women aren't allowed to be priests.  I know a lot of former Catholic men and women who say one of the reasons they just don't participate anymore or have even moved to another Christian denomination, is because of the way women are treated and do cite the issue of the male priesthood and the all male patriarchal church.  

Some people care very much about this issue and some not at all.   As with most things, there is no one answer that speaks to everyone.
