To the OP,
Couldn’t you just arrange a meeting with the judge/prosecutor and explain your circumstances / detrimental career effects and try to get it changed down to a basic rules violation, warning, or speeding 5 miles over, etc., in exchange for a bunch of community service time and a fine or something like that? That would keep it almost irrelevant on an application. If not, keep fighting it, reducing it in any way you can and don’t get any other tickets for anything else either. I knew some guys at flight school way back in the day that would try this to varying success so worth a shot...
Also, the guy calling you an entitled whatever is a little obnoxious and I’d ignore his commentary personally, but as others have indicated there is room for improvement in terms of maturity in your response to the incident. Like they say, you got to own this. Try to see the world in more of a big picture POV...
Good luck. Handled properly and maturely this shouldn’t be too much of a problem for you.
