You’re suffering from two serious problems here:
1 - you listen to Bill O’Reilly. He’s an idiot, blow hard jerk, self aggrandizing liar. Don’t watch his show, it just encourages him to tell more stupid lies, and it eats your brain.
2 - you believe a bad conspiracy theory, not only that but a pointless conspiracy theory. The reality of it is that Oswald probably did kill JFK, and even if he didn’t, it was 49 years ago, who cares.
Walk away from conspiracy theories, run away from talking head dipsticks like Bill O’Reilly, you’ll quickly find your life becomes simpler, and more enjoyable, and you’ll get smarter.
Thank you for well made points
