There was nothing wrong or out of the ordinary in the style presented by the OP. What made the thread devolve was people's past perceptions of the poster, a generally negative perception. Many of us also do not believe the poster to be the type she says she is, so when she speaks on that issue some will immediately discard what she says for feeling it lacks any credibility or true insight, and thusly, a devolving discussion is born.
Dude, you are confused... there was everything wrong with TG's original post. She boldly stated (and repeated a few times) that her own perspective was that of all ENTJs. Not only is that not true, but even if she WAS an ENTJ, she has no business making that kind of claim. She is her own unique person with her own unique perspective and she should not irritate other ENTJs by telling them who they are. KTHX.
