INCOMPATIBILITY ?

The United States--though, predominantly Christian--is a nation that spans the religious spectrum; even, some Americans are faithless or, atheistic. In America,unlike many other nations,the rights of women are equal to those of men. Included in the population are homosexuals; among them are transsexuals, transvestites; their civil rights are the equivalent of all other Americans. Recently, same-sex-marriage became legalized. Many Americans are lovers of dogs; dogs are common in near all areas of American society. With these, and a myriad of other realities, all being concomitant to America, it does seem incomprehensible that--except those who are, already, patriotic American citizens--a practicing or devout Muslim, who is a current citizen of a Muslim nation, could find America the least appealing. Why would a devout Muslim, of a Muslim nation, extend to extremes to migrate into American society, where a multitude of indications appear conclusive that, the American's way of living, their values--their habits and practices--seem not embraceable to a Muslim, dedicated to the tenets of Islam?
