But The thing those who don't know about Islam and Muslims practice will think that having a Beard or Veil is seen as extremist... But It' s not. A beard could do few centimeters or less or more and the Veil is something awoman will wear, that's the basic knowledge in Islam. Veil have been used since the beginning till this day. It' s not in anyway Extremist and it will never be.
BUT Muslims HAVE the right to wear it or not... That's a right with themselfs and should not be imposed or restricted in anyway.
As the "Today young do not wear or do that" it's already happening in Muslims majority countries, where Woman do not wear a veil or a guy to not have a beard...
TBH the Beard and the Veil will ALWAYS exist till the End, maybe less when you are young...but in the old age... A good majority choose to...
AND LAST thing... The veil and Beard do not come form ARABian society... It's from Religious book. So whatever you are arab or not... it's only based on religion.
SO IF CHINA want to get ride Terro views... the only way it's to let them practice their religion freely and peacefully and USE THE MUSLIM community to fight with you AGAINST those Terro... because THEY ARE ALSO OUR ENEMIES! since their true name in ISLAM is Khawarji, meaning " Dogs of Hell" our own prophet asked us to fight them till our last breath... they are the cancer hiding among us...
And all along our history... those Khawarji existed and we always fought agaisnt them... They even Killed one of most Important Person in Islam...
