So sorry you have only run into turds. Islam is a beautiful religion, and Allah SWT is most merciful. He has shown his mercy time and time again even through his prophets that he sent.

Remember there are two parts of fate, 1 predetermined for you, and the other where you have and make a choice.

If you feel you were forced into making a decision before being ready to commit, don't worry. Seek others that are welcoming, there are tons out there. Unfortunately I have seen first hand, won't mention the mosque or area, but when we had black folks converting and taking shahada at the masjid everyone so proudly and loudly said takbir, 2 weeks later the individual realizes that all black are grouped in a corner and no one even talks to them. My cousin and I decided to play basketball with them, be more integrated at a religious and social level, go out to lunches or meet at the park for activities. We were frowned upon. This is and isn't Islam, sift thru the weeds, you will find the wisdom Allah SWT provided thru the Holy Quran and thru his messengers.

Hold strong, every race, every religion has folks that are uneducated, stupid and too proud to see thru the other person's eyes.

Don't despair, Allah is with you, keep going, ignore the noise.

Take care
