I'm not an American citizen but I do know Sharia law is a foreign law that should be refused out flat anywhere in the Western world. We should never consider it an alternative either. We have our own systems, rules and laws to embrace dignity and freedom. Countries have fought hard and lost many to get the freedom we deserve. A country cannot operate under two systems and would tear us apart. Leave their 7th century laws to the developing worlds. It doesn't stay with us.
No, Sharia law should not be allowed in US court cases, because we should not allow a minority group to operate under their own law instead of our own. We have our own rules and standards in this country. To allow Sharia law is to give into the terrorists. We love the liberty that we have in this country.
We have a separation of church and state in America, and Sharia law, as well as any other religious law, should never be practiced in the courtrooms of the United States. This applies in all and any cases, and it is our duty to take religion out of governance worldwide.
I do not believe Sharia law should be allowed in US court cases. Sharia law was not created within the United States and it does not apply here. The only laws that matter in court within the United States are the laws that were enacted and created by this government.
Perhaps the asker of this question is not familiar with the American judicial system. I'm hoping that's the case. Because otherwise, there is no excuse for such astounding ignorance of the First Amendment, which draws a line between the government and religion. Sharia law, like any other religion's laws, should not be allowed in US court cases.
