You seem really anti-arab, which i think is quite laughable in itself. As much as you think 'they' have destroyed us, your missing the fact that our prophet (saw) is arab, infact in your way of thinking, this dilution can go back to him after all he sent his companions who were being prosecuted by the quraysh to ethiopia and it was through them that islam was introduced to East africa.
Some of the points you've mentioned such as free-mixing are basic fundamentals of islam, mingling with the other gender brings fawahish and with that comes sin. Why do you think Allah tells us not to go near zina, because once you are near it, it's hard to turn back from! With the way women are dressed at somali weddings all made up and smelling nice you can see how this is trangressing the boundaries of 'being near'
your other point of so called "hatred" is again another fundamental part of islam, It is part of our faith to reject any other religion except islam, infact all other religions adopt this way of thinking, all religions denounce the faith of others, this isn't a new concept. Also your point on oppression of women, the somali culture historically has always been opressive to women. Women who got divorced had to leave their children behind simply because they were financially unfit. Women had to work extremely hard whilst the men mostly did simple things such herding goats, housework was defintely not split evenly. Also it was seen as morally correct to beat your wife!
the somali language is like any other language that will undergo language change it's inevitable.The more contact a language has with another the more it will change and there's nothing to stop it, i think you views that the language is being raped and adultered is exteremly far fetched. Pidgins and creoles were the only languages in history, where people were forced to learn a new language and adapt, from what i've seen no one is forcing somalis to learn another language!
