Arguments for a Persuasive Essay (quote by Browning)

I need to write an essay on whether I agree or disagree with a quote.
The quote I've chosen is "Ignorance is not innocence but sin." (Robert Browning), and I am disagreeing with the quote.

So far my ideas are: As a first point, to define sin, that sin is an act against ones morality and that ignorance could cause a sin,
but could not be a sin and so it's innocence.
Second point, ignorance is not a sin unless one willfully chooses to be ignorant.

Are my two points strong? And any suggestions to what I could write as a third point? Any help or advice will be greatly appreciated.
Thank you.

No edit button? Anyways, I don't need help anymore.

I'm glad you came up with the arguments you needed on your own. If you want feedback on the essay draft, just post it here. Good luck.

Hey, I agree with your disagreement with the quote!! Good job. Remember to be very clear about your thesis statement, and also be sure to spend a paragraph refuting the counter-argument. Good luck!!!
