Well, it's already been discussed how he would hardly have been alone in thinking them uninspired, even among saints. For example, Jerome caved (in his deeds), Luther didn't, but they were of a like mind on the issue of inspiration. There is also the matter that the Jews themselves threw them out well before they were canonized in any sense. Of course non-Christian Jews will throw out the entire NT, but that is apples and oranges compared to their view of the OT.
First of all, Luther also caved - he didn't remove James.
Secondly, don't you get it? Your continued defense of the removal of the Deuterocanonicals is based on the Jews - who denied Christ. Is that whom you will side with? How often must I remind you that you are siding with the Pharisees who rejected Christ and the Christians??? In you rush to condemn the Church and anything Catholic, you commit intellectual suicide and don't even realize it...

You explained why Luther could doubt the inspired character of the Deuterocanon, but you do not explain why did he take the unprecedented step of declaring them uninspired, and why did his followers remove them completely.
