Racism will always be around. There will be blacks who wont allow blacks to marry whites and whites wont allow whites to marry blacks. South Asian people wont allow their kids to marry different cultures, just as Chinese and the whole others wont allow these types of marriages either. There will be segregated churches, just as their are segregated mosques and this is the reality of it. No one should leave their deen (religion) because people, not our deen (religion) have made these decisions within themselves. Allah SWT says Surah Al-Hujurat, Chapter 49 Verse 13: “O mankind, indeed We have created you from male and female and made you peoples and tribes that you may know one another. Indeed, the most noble of you in the sight of Allah is the most righteous of you. Indeed, Allah is Knowing and Acquainted.”
Islam, The Quran states it beautifully that we are ONE and not disconnected nor should we be segregated but we have done it upon ourselves and this is just not Islam but this is ANY religion and even those who do not follow religion. No one has anyone to blame but themselves for these things that are happening. We as an Ummah (nation, community), whether you are Muslim or Non-Muslim be more open minded and teach to all aspects of life, in order to people to embrace the true meaning of Al-Islam. Islam says to be easy with the people. How do you think so many people in the time of the Prophet Muhammad (Peace & Blessings Be Upon Him) accepted Islam? Was it because he was harsh with the people? No, he was easy and he was patient. Do not blame any religion for peoples misguidance but look to the sources and find those who don’t practice the religion like the hypocrites and then deny Islam in their hearts but someone who practices it, lives and believes in it and strives to the best of their ability.
And Allah SWT knows best
