All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.
We have already explained in Fatwa 84769 that Islam has prohibited racism and treating people on the basis of race, color, and so on, and that it fought this and considered it as a reprehensible act. Islam considers faith and piety as the basis for a person being better than another, so please refer to the above Fatwa. When the Muslims applied this in the early times, they conquered and ruled, and when they ignored these principles, they became weak and humiliated.
Therefore, if those sisters are treating you in the manner which you mentioned in the question, and those brothers are treating your husband the same way you are treated, then those sisters and brothers are very wrong. Hence, one should advise them in a wise manner and good admonition, hoping that they would return to the way of right conduct.
As regards the Taraaweeh prayer, it is a Sunnah and not an obligation. Besides, the woman's prayer in her own home is better than her praying in the mosque as the Prophet said: "…And their homes are better for them." [Abu Daawood] Therefore, you are not wrong by not performing the Taraaweeh prayer in the mosque.
With regard to the ‘Eed prayer, it is a confirmed Sunnah, so it is recommended that all the Muslims go out for it including the women, even the menstruating women, who should witness the good and the gathering of the Muslims but they should not perform the prayer (as they are not pure).
It was reported that Umm ‘Atiyyah said: “The Prophet ordered us to take out for ‘Eed Al-Fitr and ‘Eed Al-Adhha prayers, the adolescent girls, the women in seclusion and the menstruating women, but ordered the menstruating women to keep away from the Musalla (the place of the prayer).” [Al-Bukhari and Muslim]
Nonetheless, a woman is not sinful for not attending the ‘Eed prayer. However, if you can overlook the misconduct of those sisters and attend the ‘Eed prayer, then this is better.
Finally, we do not know what you mean by the chanting that takes place after the ‘Eed prayer; if this chanting is Islamic songs and the like as a way of celebrating this day, then this is permissible, but if this is a kind of Thikr (mention of Allaah) that is done as an act of worship, then there is no basis for it in Islam; rather, it is a kind of innovation and it is not permissible to attend it.
Allaah Knows best.
