"I can't fix anyone"
Exactly
"And a person can only fix himself if he is willing to take the time and effort to do so."
Many of us have many things to "fix" in our lives - why don't you let US figure out which ones get the priority - time and effort disappear quickly.
"I simply pointed out errors which caused more errors."
And quite frequently, folks like yourself, are unable to see the forest (big picture) because you can't look past each tree (punctuation)
Without trees, there is no forest.
I should probably stop here; but I feel it is incumbent upon me to try to help someone who obviously wants to communicate ideas he/she feels are important.
Written communication is worthless if not made up of standard spelling, grammar and punctuation. For many of us, writing is not just a spewing forth of thoughts regardless of the manner in which we state our ideas. Those, I believe, who take the time and make the effort to write intelligibly are those who succeed in getting across their message.
We have spent too much time dealing with this issue. If those to whom the original response was made had taken time and effort to write clearly, I would never have responded at all.
