If I was an employer (regardless of state), and I had access to both your Police Record and your PPRuNe posts, I would probably overlook your DUI, but then positively exclude you on the basis of the way you conduct yourself online.
I would assume that your online etiquette (or lack thereof) might reflect your flight deck CRM skills, which would preclude you from any consideration of a job offer.
Have a think about what I've said and report back in another 2 years - if you're still in the industry... If you're not then my first impressons were correct.
If you don't understand what I've said, then think about it for another 2 years. If you still don't understand, then yes you do need a different career.
Kind regards,
Fred
Good luck.
