Is there no problem of following gentile statutes?
Or of “the ways of the Amorites”?

Rabbi Michi, my question was about the logic behind the adoption: is there some reason for it, or is it just a meaningless phenomenon with no significance at all? Is this about a desire to resemble gentiles, etc.?
And regarding the Rabbi’s answer: does the Oral Torah, by definition, not include customs but only laws?

P.S. What relevance does the “aqiqa,” which in our holy tongue is called “halaka,” have for us?

Tam,
It seems to me that the prohibition of gentile statutes applies to things that have no reason at all. If there is some reason, then the prohibition is not relevant.
Although with the halaka haircut one could argue that it falls under things that have no reason, one can still say that after all, people do not cut a very young child’s hair everywhere in the world, and only from a certain age do they begin grooming him. So we simply adopted the age of three, because at that point he is more mature and they are already beginning a bit of his education in the commandments.

R.Z.,
Take a look at Babylonian Talmud, Sabbath 65–66, in the recent Daf Yomi cycle, regarding “the ways of the Amorites.” It seems that things which had some benefit, but a segulah-type benefit and not a conventional benefit, are considered by the Talmud to be “the ways of the Amorites.” The halaka issue is really just an unsuccessful example, but the principle concerns things whose benefit is not visible to the eye, but is of a segulah-type nature.
On a timely note, I heard there is such a thing called “frankincense wood,” and masses of our chosen people went to buy it as a segulah advantage against coronavirus, based on past claims (whether true or not I do not know) that it supposedly helped against viruses. And here the question of “the ways of the Amorites” seemingly comes in.

Correction: the Daf Yomi from yesterday or the day before, not from last year.

This is not “the ways of the gentiles,” just as wearing pants or glasses is not “the ways of the gentiles.” As long as there is logic in the custom itself, it does not count as the ways of the gentiles or the Amorites.

Honorable Rabbi, the halaka haircut was an unsuccessful example, but the question is about things that have no apparent logic, such as various segulot. See what I wrote above regarding frankincense wood and coronavirus.

To Benjamin, he said—

Never mind that they learned the “halaka” haircut from the Arabs, since it is after all just a haircut, and there is also the aspect that the one getting the haircut becomes like everyone else. But what will you say about the custom of drinking coffee, saturated with caffeine—why, that is truly “the ways of the Amorites”!

With blessings, Samson

Though there is indeed a hint in Scripture to drinking two cups of strong coffee, as it is written: “Hope to the Lord; be strong…”

Things that have no reason should not be done even if they are not taken from gentiles. Simply because it’s nonsense. And if they are gentile customs, then there is the added prohibition as well.

Is the Rabbi opposed to the halaka haircut?

I do not see any point in it. In my opinion it is definitely unnecessary, and if its source is among gentiles, then perhaps it is even forbidden.
