"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."
This is not why the older generation has more sway. Calling just means talking to an intern who will read you the boilerplate, and then mark down a for/against tally if you're lucky. Most of them don't even care about that since they're ideological motivated rather than caring what constituents think.
