Not so much a matter of boycotting NY, but rather telling weapons companies in non-free states that they need to relocate, they need to stop selling to NY,etc.
Do you *really* think that large industrial businesses in general care?
They are going to make rational decisions.
What do you think it would actually take to move a business the size of Remington or S&W?
What do you think it would cost?
Does anyone REALLY think that companies who sell products to law enforcement and government users will "bpycott" them to send a message?
(and "Yes" I know that Mr. Barrett did it to California, that was a very small and special case).
There is no rational business management team that would do that to "send a message".
Thinking that this is a practical possibility is another branch of the tin foil hattery tree.
