This parent-commenter is correct, ASL is a completely separate language from spoken English. Many people who are raised with ASL as their first language prefer seeing ASL rather than reading English.

Modern ASL includes elements of "signed English" but it it's own language, the third most common in the US.

I am a hearing person, so take my understanding of this with a grain of salt. Here is a Deaf primary resource to describe the difference.
