Mitzvos and Aveiros that are in the realm of thoughts and personal feelings, Avoda, etc are not “Hashkafa”. They are “Halacha”. Anyone who isn’t a complete Am Haaretz can easily cite a plethora of sources.
Is lashon hara Hashkafa?
Why should Histaklus, Lo Sasuru, Bitul Zman, virtual Torah , Moshav Leitizim, miynus , etc be relegated to the category of “Hashkafa” and lifestyle choices ?!?
Perhaps there are “frum “ educational systems that teach that some of these topics are not Halacha but rather “choices” within orthodoxy. That would explain the attitude. Avira knows….
