I get to think and say whatever I want as long as my First Amendment rights still exist. You get the right to disagree and think and say whatever you want. I sincerely hope it's how things will remain, and so will all our other Constitutional rights. Because I witnessed first-hand what could happens when the Constitution becomes a piece of paper, and I hope that no one would ever have to experience that.
But more than this, I'm curious what logical connection have made you bring fentanyl into the discussion about purported government surveillance of illegal migrants and possible side effects of this on US citizens and legal permanent residents. Seriously, why have you even thought of it?
