Without replying to the actual thread (yes, social media is probably the scourge of our generation, Jews and gentiles alike, darn, I just addressed it) Reb Eliezer’s point about the mezuzah is dead wrong.
“There is an argument between Rashi and Tosfas how to place the mezuzah, whether to place it horizantily(sic) or vertically. We compromise by placing it slented(sic)”
No.
The Gemoro (Menochos 33a) says עשאה כמין נגר פסולה
if you placed the Mezuzah like a bolt/peg it is פסול.
The Machlokes between Rashi & R.Tam is what type of a bolt the Gemoro is referring to. (vertical or horizontal)
The Machlokes is not which position one should place the Mezuzah but which position not to place the
Mezuzah so that it is not כמין נגר.
All agree as long it is not positioned like a peg it is כשר.
Positioning the Mezuza at an angle is not a compromise (doing it halfway like both) but is the proper לכתחילא way to place it, (according to both) being a peg is never placed at an angle.
Just thought I’d clear that up for you.
