“Rav Moshe’s shitah is clear and constant: Six hundred thousand people on a street makes that street a reshus harrabim. The same number out and about in a city, makes the public places of the city into a reshus harrabim. Precisely how to count a city is of no consequence, because if it is close than we are unable to guarantee that the eruv will contribute to shemiras Shabbos and are exempt from building one.”
Gibberish. Besides you obviously do not know what a sratya is. No. Rav Moshe shita is not clear, and it changed over the years. You constantly lie about it, because you do not know what to do with the inconsistencies. How to count a city is stated clearly in Igros Moshe, stop lying about it. In fact Rav Dovid agreed that his fathers shita is three million, when he allowed the Chicago eruv. In fact, the absurdity was on full display in Chicago. The anti-eruvniks argued that they disagreed with Rav Dovid regarding his fathers shita. Only those who osser can disagree with him.
“1) So you are left wondering about Rav Moshe’s intentions with his Flatbush teshuva. Because there is no chance that you are wrong here. But you won’t wonder about it either. We should ask Rav Moshe to wonder for you.”
Childish
“2) Rav Moshe writes that he is forced to write about Flatbush, because people think he permitted it. What compelled him? Is it possible that he believed that people are not allowed to carry with an eruv based on a mistaken belief of Rav Moshe’s permission?”
That is exactly it. Nevertheless, he stated clearly that he cannot issue a psak din barrur because he is mechudash and is arguing on the poskim.
You can split hairs now.
“3) Comprehension alert! Without Rav Moshe’s opinion, there is less of a reason to build an eruv in a mega-city. The simple understanding was that a population of 600,000 makes the city into a rsh”r. Rav Moshe is bringing about new ways to be lenient throughout his teshuvos.”
Totally incorrect. Rav Moshe understood that shishim ribo is conditional of the street, but then came up with his chiddush. So in fact you are arguing on Rav Moshe. There is no posek of stature that maintains that shishim ribo is conditional of the city, besides for Rav Moshe. Hence, Rav Moshe is machmir. Even the Mishkenos Yaakov understood that it is conditional of the street.
“So take away his chiddush and try to use the Aruch Hashulchan. (Except that the Aruch Hashulchan is trying to incorporate the Mishkanos Yaakov into the accepted halacha. [Meaning, that the sugyos go according to the Mishkanos Yaakov, but the halachah is different because of his chiddush.] But I doubt that matter is a factor to you.)”
It is not a factor, because it is not the Aruch Hashulchan’s chiddush, but only Rashi himself, and other Rishonim (Eruvin 59b). Furthermore, there are many other reasons to allow, such as mefulash umechavanim, and mechitzos.
“Nobody is adding to Rav Moshe’s opinion to forbid the eruv. And there is no way around it. His shitah is very straightforward, as it appears in chelek aleph.”
You simply do not know what you are talking about. Just one example: Pirtsos esser. According to the anti-eruvniks of course Rav Moshe maintains that it is d”Oraysa, but Rav Moshe maintains that it is me’d’rabbanan.
“4) A thourough review of Rav Moshe’s writings, show that many of his rulings were not given with a horaah lasos. Rav Moshe was very humble about forcing his opinion on others.”
Irrelevant
“You can still build any eruv you want. You can even put up an eruv in a bungalow colony, that nobody will check for years on end. You can build an eruv without knowing the topography. I don’t care.”
Sure and throw out hilchos eruvin. This is what the campaign opposing eruvin achived.
“But don’t go around proclaiming that Rav Moshe’s shittah is not definitive, when Rav Moshe clearly says it is.”
His shita changed, and his psak was based on incorrect information.
“As he told Reb Tuvya, you can disagree with him. But at least make the effort to properly understand the teshuva.”
And Rav Tuvia believed that Rav Moshe would allow the current eruv.
