What do I need to move to Denmark and become a citizen?

I’ve been a uk citizen since i was a child and omg it’s terrible, tons of drugs tons of crime and dozens of anti lgbt groups so because I’m trans I’m not very liked so I’m hoping to move country to an actually good country

Btw I’ve never traveled in my life let alone tried being a citizen in a different country so I have no clue where to start yet so any advice is appreciate it lol 😂
