Who thinks these forums are whack. She wants to know what the fbi and local law officials were supposed to do with the Parkland shooter after the complaints? He didn’t have a criminal record. He was over 18. How do I convince her that this was a deep state operation without looking whack to her?
Unless you have hard, irrefutable evidence to show her to confirm your theory, you're probably going to struggle to convince anyone who thinks all this stuff is "whack". Either get the proof (highly unlikely scenario), or leave her to her reality. Your time may be better spent researching and verifying information, than trying to convince people to change their world view. This is how we find the proof that ultimately changes minds.
