Doug, I am not saying all American women are of the same ilk as those depicted, although I suspect those who marched would be. You say you would support Sharia law within the Muslim community, although I am sure that you would not support child brides, female genital mutilation and the killing of homosexuals all of which are tenents of Sharia law.
Well, I certainly would not conduct myself in that manner, but if my religion required I do that I might. It seems to me that Islam is a religion of extremes. In that respect I would expect that even within Islam there are those who do not practice those acts.
The U.S. has a long history of trying to "absorb" various religious beliefs...Mormons may have multiple "wives" under certain circumstances (many of them "child brides") and the Amish persist in holding on to the past, preferring to get where they are going in horse-drawn carriages rather than automobiles. We have a community very close to where I live that is primarily Mennonite and they run their own schools, own the buildings and all. Only the children of the local Mennonite population can attend that school.
Religious "tolerance" has long been a practice here...right or not. For example, many of the immigrants from Nigeria will send their daughters back to Africa at some point in their adolescence so that their "genital arousal area" could be cauterized (mutilated, as you stated!). It wasn't done in the USA, we don't sanction that kind of act, but we do tolerate their religious practice rather than try to deport them for having it done. We even have a rather sordid history of mistreatment of homosexuals, some of which has been lethal, but none of which has been sanctioned by any western religion of which I know.
So...all of the things you mentioned have been part of the American experience over the decades...for bad or for good, depending on one's point of view...some of which is developed as a part of their religious training.
I don't see how we can avoid it...but we have to be aware of it and vigilant regarding our efforts to stop it.
Maybe President Trump can figure out how to build a wall around America that will keep out only the bad Muslims out and let the good ones in...
When Muslims lobby to attempt to get Sharia law implemented for us ALL, regardless of religious affiliation, we'll see a stop to that here, where religious freedom (freedom to practice ANY religion, or NONE) seems to prohibit the establishment of any laws that favor one religion over another, which implementing sharia law over non-Muslims would do. Within their own "community/culture", however, we have no right to prohibit them from establishing their own religious customs, complete with genital mutilations, in the name of their religion...within limits, of which I would suspect the murder of homosexuals would be a crime according to our laws.
What a mess!
Cheers?
Doug
