"Thank you for your thoughts on this matter, I didn't read them. Here is a boilerplate statement espousing all the great things about this bill that you specifically criticized in your message to me. Please don't reach out again."
Trust me, hearing isn't the same as understanding. Senators, executives, billionaires, etc are all the same. They're used to their power and they are unwilling to actually understand people like us.

But civic engagement also involves the easy stuff, so it shouldn't be written off as pointless
