This is the one true talent of the left - splitting hairs (and communities). If you’ve engaged one of them on a blog that is advanced beyond pure vitriol, you’ve been witness to the hyper-parsing that they enjoy.
They live to slice those commas! No matter how clear and unambiguous a quote, a citation, or a statute is, they “discover” nuances in the language and exploit it to fracture the common understanding (see Roe v. Wade).
It happens every day and on every subject, and our most sacred traditions like the US Constitution is their greatest target with the 2nd Amendment being the holy grail.
They will never stop the assault so we must never stop our vigilance.
