why people want to mingle freely with strangers of the opposite sex,if you find somebody likeable propose to him or her and get marreid and 'mingle' as much as you want,Islam happens to be the religion of most of the people here,and it doesnot allow dating ,courting or cohabitation or anything of that sort(out of wedlock ofcourse),and frankly there is no compulsion in religion and be assured nobody will try to change what ever belief you may have,but do not expect the society as a whole to be compatible to your account of being normal
