What concerns raised about the law’s “incompatibility with Judeo-Christian values” are worth listening to?
The issue isn't that they are compatable, it's that both Judeo-Christian values and Shria Law are two sides of the same coin. Religious restrictions imposed on others.
Also, the last sentence is an especially stinky take: people are allowed to impose discipline on themselves without demanding others follow the same (like gyms and diets).
Not saying they can't. The framing that that he's practicing Sharia law wasn't the best thing to say in response to the allegations. He could have said, "Sharia Law doesn't require A,B,C." Instead, he said made a general claim about lies and how he is currently practicing Sharia law, further validating the criticism against him.
