I wrote the following as an example:
There are Christian men who pretend to be virtuous while at the same time committing sins like adultery like it was nothing. I say "Blasphemy!" However blasphemous it is, non-Christian men do so too, so this is a criticism we can raise against all men and not just Christian men.
I am wondering if it's better to keep the exclamation mark inside the parenthesis, or put it outside. I seems more natural, but I said it's better to keep it inside.
