1) I know Rabbi Sapirman is close to and is guided by Rav Shloime Miller. Rav Mattisyahu gave his Haskomah because of Rav Shloime's recommendation as is stated clearly in his Haskomah.
2) Im not making excuses, I was just wondering why the language seemed to be so strong given the facts that I know.
3) I sat through an 8 hour training course for mechanchim and you are wrong; He does NOT walk into schools and propose questions, he DOES offer chizuk presentations for students which often end with extended Q&A sessions where he offers answers to the questions the students have (they do have questions btw, he doesn't propose anything). And this is not his main focus at all, the CD's and training courses are not for kids, they are for parents and educators (as you so beautifully pasted above), perhaps have a listen before ranting.
And btw Harav churnbabychurn, just because this is a "pet peeve" of yours and that you decided that "Er shmeked mir nisht" (as you stated earlier) doesnt mean its a mitzvah to publicly crusade against anyone especially when you are uninformed about the facts of the matter.
