Yes,I've heard that argument made.However,the sites with which *I'm* familiar note that a post has been edited and when it was done.So if someone here accidentally posts that another Freeper is a dirty stinker he/she can catch the error and fix it to read "you're *not* a dirty stinker.And if the offended person replies angrily he/she can then realize the original post was an error.
Exactly….and not only do the time and dates of edits appear, but if anyone quoted them - that language does not change.
But then nothing stops the changing of posts of consequence. And the original statement is gone.
Think if the Dan Rather post had been changed/erased (not that it would have been but for example). and in its place “Post edited”.
