With respect, I submit that from what I know this was not a "knee jerk reaction" by GM. But a boycott that plays right into the hand of our opponents certainly is.
We all know that "the full power of the law" cannot always protect us. Isn't that why we choose to be self-reliant when it comes to defending our families and ourselves?
I'll bet GM has done plenty to support gun rights, most notably supplying good products at reasonable prices.
Nobody has an obligation to be a martyr for my cause.
