No. Wall. It is a hate-feeding, fear-mongering, preposterously ineffective, appeal-to-the-worst-in-us campaign tool. Let it go. Fund schools instead. Public schools. Keep the environment clean and find ways to encourage the already booming employment opportunities in the clean energy field. Study healthcare and strive for improvement, not repeal and replace pissing contests. Stop sinking into the mire of putrid rhetoric. It's time to rise up.
