I gather there are some concerns, particularly among conservatives, about the implementation of sharia law* in the United States. I don’t know how reasonable those concerns are, although as a woman I tend to feel that any possibility of such a thing happening should be viewed with great alarm.
There is, however, a simple way to make sure sharia law is not implemented in this country: pass the Equal Rights Amendment. Not all sharia law has to do with the role of women but a fair amount of it does. the Equal Rights Amendment would insure that the aspects of sharia law that enshrine different rights for men and women could never be implemented. Losing the "sweetener" of being able to treat women like second-class citizens should make the prospect of sharia law much less enticing to many who might otherwise be willing to condone it.
*I do not have a nice, clean summary of sharia law to offer as a link. The Wikipedia entries on sharia law and on women in Islam read - as one commenter put it - like a pro-Islam “tourist brochure”.
