This problem involves many factors such as social culture, psychology and women's rights. In some cultures, menstruation is considered as an "unspeakable" topic, and women are therefore regarded as a "vulnerable" group that needs protection. Under the influence of this culture, giving women a black bag may be considered as a kind of "consideration".

In addition, there are some reasons for buying sanitary napkins and sending black bags:

Privacy protection: Some women may think that black bags can protect their privacy and prevent others from knowing that they are menstruating.

Improve quality: Some brands may think that black bags can improve the quality and grade of products and make customers feel that they have bought high-quality products.

Marketing strategy: Some companies may use black bags as marketing strategy to attract more women to buy their products.

However, this practice may also aggravate women's menstrual shame. If a woman is holding a black bag in a public place, it is easy for others to guess that she is menstruating, resulting in embarrassing and uncomfortable feelings.

In addition, this practice also implies that menstruation is a disturbing thing that needs to be covered up, thus further deepening the sense of shame of menstruation.

Therefore, giving women a black bag is not a completely correct "consideration." On the contrary, we should respect women's rights and let them feel natural and free when buying sanitary napkins. If you really want to help women, you must try your best to break the shame of menstruation and make women feel comfortable and confident during menstruation.

Whatever the reason, we should see the potential problems behind the black bag and think about how to better support women's health and rights.
