How does the new discoveries confirm your statement in anyway?
Neither sample was I2a-Din. Loschbour was confirmed I2a1b* L621- L161-. The L621- means not I2a-Din, because I2a-Din is L621+. Nordtvedt places I2a1b as a whole at about 16k years old, so no contradiction. Similarly, Motala12 was I2a1b L621-, and hence not I2a-Din. It could have been I2a-Isles L161+ in theory, but could also have been I2a1b* like Loschbour. Again, no contradiction.
