One thing many of you miss is that you can't keep aside Islam from your life. If you follow Islam fully your life has to be organised as Islam tells you, you can not pick and choose what your IQ tells you. When entering Islam, enter completely.
Many scholars agree upon that men has to cover they body between knees and navel, so if you follow this rule in your daily life you have to follow it when you play football for instance, hence you can't just say keep religion away from sports, you just can not do that if you are totally committed.
Islam is there with you 24 hours and all your actions, no matter what profession you are in have to be in line with the teachings of Islam.
If other religion can be kept away from certain things just don't say the same about Islam because you have to follow Islam all the time.
I am sorry, I have alot to say about this but my english is really poor and besides I am travelling now and have only my phone to type with.
