Waynetta, I have a friend whose husband is a born Muslim and no one salaams him in the masjid as he is black, my husband has seen people say to others why are you coming to this masjid you are not Bengali, that type of mentality is about anyone who is culturally different from yourself including born muslims from other tribes/nationalities/ethnicities.
Again when it comes to marriage, if you are a born muslim of a particular country, living in an area where there are not others from that country it is hard for you to get married. In fact all people say it is hard to get married these days. I have a niece who has being looking for rishtas for 2 years and none have worked out. Born Muslims are using these singlemuslim.com and forums and stuff to get married.
Born Muslims can also get that pivitol time in their life when they conciously decide to want to follow islam and learn and stuff, most of my friends have been through this, so they also go to lectures, study, learn, organise etc
Born Muslims can also have to deal with the attitudes of their dads friends down the pub when they start wearing niqaab, I have seen this happen. Most girls parents are not happy for them to wear niqaab, someone I know who lives in Pakistan in her fourties her sister gets offended that she wears niqaab in front of her husband.
There are also born Muslims who are alone on Eid, my friend who escaped an abusive marriage would be one of them. She is a born Muslim, but has no family in this country. We do not see these people as we dont ask everyone these types of questions when we see them walking down the street, we just see an accented woman in abayah with kids and assume she has extended family here and so on.
We all go through the same sort of stuff. There doesnt have to be a divide.
