Whether you do it or not you're defending it. Do you feel its constructive? If Tylenol was killing people, would it be helpful to go on the internet and post "holy shit, this is a real problem, why don't we ban heroin"? Wouldn't ignorant bozos posting nonsense on your behalf give ammo to your opponents?
I don't give a shit if you agree with me. I'm giving you good advice it's up to you whether you want to listen. You're not helping anyone but your opponents by remaining ignorant.
