I disagree. You're not a crackpot just because you're wrong. You're a crackpot if

• you make logically inconsistent statements and adhere to them after careful correction
  
• you use thought experiments that contradict real experiments
  
• you use works of fiction as if they were facts
  

• you compare yourself favourably to Einstein, Newton or Feynman
  
• you compare yourself to Galileo and your critics to the Inquisition
