I think you're right here Steff. Whilst leaders of the community and religious and altruistic Muslim organisations have strongly spoken out and condemned the attacks, there does seem to be a fear within members of the Muslim community to speak out, maybe due to intimidation. Just another theory, but in my experience Eastern cultures are very private and enclosed when dealing with issues, large and small, within a family unit. For fear of bringing 'shame' to their family into the community. We have seen instances of 'honour killings' in predominantly Eastern cultural nations and very sadly, there have been cases of young women being killed in the UK in these communities.
I wonder whether, for fear of 'shame', elder members of a family will not speak out if there children are being courted by extremists? This sort of attitude has no place in the modern world, as is being shown by various protests and marches occurring in Eastern nations by mostly the younger generation. It certainly does not belong in Western culture, where our core liberties are that of freedom of expression, speech, sexual preference, gender equality etc. My mum is a very forward-thinking, Westernised Indian woman, but even I ended up at loggerheads with her in my younger years due to what I perceived as a very 'stone-age' attitude to certain issues. Nothing serious, mostly petty stuff but it still frustrated me that we were living in a Western culture and she was still unwilling to adapt to certain ways of life.
My point being and as is always mentioned after events like this, one must adapt to the local way of life if they leave their own culture. By all means, keep your core values but what is the point of leaving one place for pastures new and not developing your mind and soul to integrate with a new culture and way of life? Members of communities must have the strength to realise that they are no longer in a potentially oppressive environment and WILL be supported if they speak out. We're renowned globally as Brits for our support of all ethnicities and generosity of spirit, which I am proud to have witnessed on many occasions in my travels.
