It's a Discussion.
"2 people dissed you on your reply."
No one was disrespected. Everyone put in some content on the way to figuring out why your client might feel this would be useful or why you are uncomfortable that the resources you found and have been given didn't meet your level of evaluation. We all are used to working together in this virtual environment. No one disses someone for asking for more justification. We simply try to provide it.
I happened to teach that very thing in my Payroll class. We discuss why you don't need to be in my class in the first place, because "payroll" and "employee" don't apply to a sole proprietor. No one ever asked for IRS citation, though.
"Level Up" is a gaming function, not a real life function.
