Why other people feel Islam is dangerous ?

Islam prohibits some issues that modern people like to do such as music, in Islamic view music has nothing to do good but occupy people's brains with unnecessary feelings, people can easily live with out music.The next thing is only an oath can't do,  people hate to give hard proofs such as examination can reveal how much you learned and took seriously from the teachings, pass or fail is not a matter but people are serious about results. Using all physical and mental issues for good purpose is really hard to practice but Islam will not allow you to do them in even subtle distorted way. In Islamic way you should improve day by day with out trying hard, your family and society along with a nation can make all issues as simple as weather pour anything all over the world. So living in Islamic society is the full proof formula for human beings but people afraid to do so because there rigorous punishment available for doing wrong willingly.
