No you didnt.
Most of it was the usual misdirection stuff that you have done before. Other parts are based on a book that you cant even validate (the Book of Mormon), which has an extremly questionable origin and should rightfully be regarded as a work of fiction.
The part about God changing the DNA of the Lamanites was interesting.
If you believe the BoM, God can change a races DNA. But God appears to have no idea about smaller things like grammar, spelling, human languages (much interperating them) which required His book (the BoM) to have multiple editions and thousands of corrections.
Of course there is also the point that there are no original texts that we can verify the BoM translations against, although that could arguably be put down to a question of faith, but that also means that there was no original source to use for comparisons when corrections were done to the BoM. Which raises questions about how it could actually be corrected at all!!!
Even the part in the Book of Mormon about the Lamanites being the principal ancestors of modern American Indians is a correction, it used to be that they were the sole ancestors of modern American Indians.
I am sorry, but you are going to have to do better with your DNA argument (especally with your dismissal of critics not being scientists, where exactly did they get this lack of DNA evidence from?). Since it is quite apparent that the BoM is at best an unreliable source (an observation that you and other LDS have not been able to disprove), it cant be used as a source to discredit the lack of DNA issue (or any other LDS issue really).
