I have an idea - how about not playing the adhan for every prayer, rather just for the Jum'ah friday prayers. Only once a week during Midday, not so bad.
But personally, I am against making the adhan 5 times a day. This would only make serve against Muslim interests and only play up much more anti-Muslim sentiments amongst the wider British populace and the whole "Eurabia" crap and is not necessary. At most, a single adhan for the Jum'ah prayers could be sensible perhaps, a once per week thing in a okay timing. Just make sure the Mu'adhin has a beautiful voice so as to not disturb or bother non Muslims and soothe them to an extent.
Also, this move should be accompanied by a huge increase of Mosques engaging in a wide host of positive interactions with non-Muslim British society, and people like Anjem Choudry need to find their greatest enemies not in the English Defense League, but from the Muslim British populace, communities, Mosques, Islamic Scholars, Quranic teachers, and everyday people. The wider British Muslim community should really look up to Sikhs and even try to surpass them in doing things like fundraising for the local homeless shelter, having free kitchens for those who are in need of food, and serving as noted arbiters and peacemakers amongst different communities whether Muslim or non-Muslim. Some of this is already happening, but there is much good and positivism that can be generated from the Muslim community that can overturn alot of the anti-Muslim madness thats been pervasive in some circles. While it is certainly wrong to group Muslims as a monolith, it is necessary that striking a much better relation with the non-Muslim British public as a group will erode alot of negative stereotypes that can't seemingly go away despite what Muslims do. So even though it is unfair, it really is necessary that there is a large consensus amongst British Muslims to act as a group and not be so divided as commanded by the Prophet sw. It's a sad reality when a single Muslim can mess things up for countless others, so an image of in-group cohesiveness projected to the wider British society that works in lockstep in engaging in good relations with their non-Muslim peers and standing against the likes of Anjem is the only way things can improve in our current climate. Many will obviously continue to ignore this in favor of continued denunciation of Muslims and anti-Muslim rhetoric, but they will become a smaller minority as the wider British public takes notice and eventually come to see British Muslims in a much better light.
