charity

And if it is impossible to wear it modestly, are we saying that it is better for someone who already walks immodestly to be ashamed of her clothes just because we did not want to help commit an offense?

If you can't, then no. Would you donate pork to a poor person?

This is not the correct analogy in my opinion. The correct analogy is would you donate pork to a poor person who already eats pork…

Moreover (maybe I'm wrong) meat is a Torah prohibition and the ramifications of the obligation of modesty are only rabbinical, so perhaps there is more room for leniency when standing in front of a poor, ashamed person.

Modesty is an obligation/prohibition of the Torah.
Indeed, I was talking about a poor person who occasionally eats pork. There is no permission to give him pork as charity.

Okay. Thank you very much.

Why should a woman modestly observe the Torah? Because she is blind before the Torah or because of something else?

According to this response, the rabbi is probably truly an educator.

An article by Shnarb that there is no modesty. Have we forgotten the great Rabbi? Has the Rabbi changed his mind?

There is no such article, and as far as I remember, I never wrote that I agree with what was written there.

Hello again, Rabbi,
I saw in Tractate Shabbat 3a that he wrote that the Gemara established the law of the helper only in the Hebrews of Danahar, and here there is only a prohibition of the rabbis alone.

So, if we are talking about girls who will not behave modestly anyway (= a monk who will drink anyway), if I give them the clothes, I will only violate the rabbis. On the other hand, if I throw the clothes in the trash, I will violate the Torah, because these are good clothes and Tequilin!
And why did they say, I am a rabbi and I reject the Torah? I wonder.

From the Torah, the meaning is the prohibition: "Do not corrupt."

This is not a Toss. This is a division that the Gemara itself says in 6:2. The innovation of Toss (and other rishonim) is that there is a rabbinical prohibition even in the Hadith of Ibra Danhara.
Throwing immodest clothes in the trash is not a bil tashachit. It is a mitzvah to destroy them. Why shouldn't you eat chicken in milk because of a bil tashachit? And so on for any prohibition of eating or enjoying food from the rabbis.
