Back in the day I had NRA stickers on my car and house. Not any more. Good way to get vandalism or worse.
As a Consulting Engineer I got hired for a 3 year assignment in Silicon Valley California. It was all based on my resume, plus a phone interview. When I arrived on site the first time I was ready to start my job (setting up a laboratory and hiring PhD chemists to pursue patented work). My first time meeting with the CEO for lunch I was wearing an NRA belt buckle. I found out later that he went along with me, but almost fired me the first day. Fortunately my signed contract guaranteed me at least 3 months with pay.
