“He also referenced the *men’s* (non-Muslim) beach volleyball uniforms. He wasn’t trying to spike the ball for Sharia.”
Since he had one example, why even bring up burkas? Why not bring up an example of Christians dressing modestly?
By using the Sharia example, he held it up as an example of virtue, and by extension the culture that forces that choice on some women and even the culture that uses violence to enforce that choice. The example was offensive and detracted from his point.
Your "by extension" is extreme. He didn't say or imply support for Sharia at all. You are exaggerating and misconstruing his intentions, and then faulting him for *that*.
Not a convincing way to argue.
