I feel that parts of your "statements" about INFJ's are poorly supported in a logically fair conception of reality as it is here.
1) Your "I suppose one shall request examples of such INFJ insanity." quotes are to say politely not valid. Here is why:
1) Your quote of Arthur Schopenhauer's writings pulls simply a few lines from a very large work to your audience's attention and try's to exemplify that because this seems "crazy" or detached from reality perhaps,... that not only his entire book but in fact that all INFJs are the same as you try to portray him to be.
2) You're saying that because this other gentleman Fyodor Dostoevsky believed that Russian soil was sacred that this means that he is crazy? Or that because even maybe he thought Jesus would return to this place instead of this place he is nuts? Using this same logic, any person who thinks that Jesus will return someplace different than you should be deemed insane. (Is that what you are trying to say because if that's what you're trying to say that's fine... I don't really care what you believe religiously, no offense, but it would help me to put to rest my concern.)
