I’m just a bachur but I am very interested in eruvin. One thing I have learned it is among the most complicated sugyos in all of halacha. I heard in a shiur from Rav Moshe Dov Stein Ztz”l (an expert in eruvin,Posek In sheor yosuv) that the three hardest masechtos in shas are eruvim, yevamos and nidda.
No person in their right mind should insert their opinions on this sugyah at least until they learn the ENTIRE sugya BIYUN-shas, tur shulchan aruch rishonim achronim -at least a year in full time beis medrash.
you wouldn’t state opinions as though you are knowlegable in pysics cemistry or other secular subjects until you studyed them thouruly so why are people willing to argue on gedolei poskim-even rishonim!! when they realy have almost no clue what they are talking about.
there are many things i have seen on this thread where people have written things as if they are a dovar pashut, while realy they are a machlokes rishonim or achronim
