Funny. Do you hold that complaint against Lincoln when tried to do the same thing on a national level? Look at the constitutional amendment he prominently endorsed in his first inaugural if you doubt me. It banned congress from any interference whatsoever with slavery in states where it existed for any reason, including emancipation. Lincoln endorsed the thing, lobbied for it in congress, and helped orchestrate its introduction and procedures all the way up to the vote. Fortunately it was never ratified.
Well, that is a convenient half truth for you.
Yes, Lincoln supported a constitutional amendment to protect the domestic institutions of the states -- read slavery.
Your note indicates how hard he worked to avoid war.
What you ignore, aithough you have seen it in thread after thread, is that he was firm "as with a chain of steel" on there being no -expansion- of slavery from where it already existed. That alone was enough to cause the war, because the slave owners knew that their "futures" in slaves and slave breeding would be compromised unless slavery were allowed to expand.
Lincoln was a man of his times. You try and besmirch his memory by holding him to present day standards. For his time, his stance was very advanced. He saw a way to at least begin to end slavery; to paraphase Churchill, he saw the end of the beginning plainly in sight. And that is what just drove the slave power nuts.
That is why they had to have war.
