Seems kinda ballsy to say F'you to 5 million customers (customers old enough to actually have money), especially in a way to imply that we are baby-killers.
Also, as is now being pointed out in the newz (though not the MSM of course), people don't join the NRA for the discounts. The discounts are generally not that great anyway. The one or two times I looked into using them (both car rentals I think) I found equal or better deals elsewhere.
We join the NRA because of what they represent. So by highlighting businesses that are no longer associating with the NRA, all the SJWs are doing is creating a list of companies for NRA members to avoid.
With the car rental companies for example, they're not getting more SJW business because of their stance (they may continue to get the SJW business they were getting pre-stance), they're simply losing the business of 5 million NRA members. Plus, it would seem, some non-NRA members who just don't like bullies.
