Typo. But then you write, 'What Lincoln actually said on that Valentine's Day in Pennsylvania was'. Unfortunately the speech you cite was made 15 Feb, not Valentines Day. If you're going to call someone onto the carpet for something, you should probably get it correct yourself.
Where?
When you stated, '4CJ will misquote Lincoln and make up Lincoln quotes. The date was incorrect, not the text of the speech. Nothing was miquoted nor made up.
If you're going to accuse someone of not knowing what they're doing it's best to know what you're doing yourself. That speech I posted was given February 14th in Pittsburg.
