I know when I hear / see something that annoys me I should look to why it annoys me. I've read, left, and reread this thread and these are my thoughts.
I didn't find the original post to reflect "we codependents...." but rather "you, you women..." and that tone is what I find - what, condescending?
If the same sentiments had been expressed in a little more gender neutral way, or inclusive manner (like the original poster counted himself as someone who acted that way too), I am ok.
I do see some of me, as a human, in the overall idea of the post.
