It’s probably for the same reason men don’t like women being «promiscous» or why some men get excited at the thought of lesbians even though lesbians don’t include them; they like it when it’s for their own benefit. If they are not benefiting from it, they condone it. Women not marrying somalis makes them pissed becuase it means that woman doesn’t want to marry them, but they will gladly reap the results of these unions, the offspring of such marriages, that is.I find it funny how most men view biracial/mixed women as the most gorgeous, irresistible and tempting women in the world and our eyes is always fixated to them but they're so rare to find.
But here is the thing, it is the men who are the biggest culprit for making them a rare breed. They restrict their women to marrying within their own only so if you view them as the most beautiful then why forbade your own daughters from marrying other ethnic groups so they can start breeding them? If everyone was open to marrying any ethnicity then we would have biracial women everywhere.
