there is nothing "appropriate" about what he's doing. It's deceitful and insulting in fact.

Besides the fact I missed the part of "Jesus is a Muslim" which is highly insulting, what is deceitful and insulting about wearing a T-shirt with the slogans in the article?

I see way more insulting T-shirts worn by Americans every day

Would you prefer him to strap on a bomb belt to made a statement?

Many of his slogans are insulting and demeaning. Not just the "Jesus was a muslim" one.
"Hijab supporter" for example, is demeaning to women. It's a symbol of oppression. In some Islamic countries, a women can be stoned to death for not wearing one.

In Afgahistan during the Tasaliban days, a house full of women were allowed to burn to death because they weren't allowed out of the burning house without a Hijab.

If you knew the meaning and reason behind many of those slogans, you wouldn't think it so harmless.

It is exactly that ignorance of Islamic "culture" that Islam uses to entrench itself into western society and slowly destroy it.
