Is Pheasant, Jewish? Christian? Noachide?
The second choice, I find it ironic that he is spreading Rav Mizrachi Shiurim (for at least the fact that Rav Mizrachi disproves all religions that are not Judaism, and has made fun of you know what).
I don't know what motivates pheasant. But as a general point.
One of the common sense reasons why one shouldn't teach people of other religions Torah, is that they will twist it to suit their own purposes.
For example, messianics learn hebrew at ulpan, and
do you remember that thread somebody started mentioning about missionary activity on jewtube, the missionary that posted the video was learning torah from some liberal rabbi's online "rabbinical training" videos.
Whatever pheasant's motivations.
It is not good for Christians to be inviting jews to listen to Torah lectures. Whether innocent or not.
And it's bad that people might not even realise that the person that invited them was really a christian.
They may think he is jewish and learn some false doctrine.
It is just wrong
