If you don't respect what Lebron is doing on at least some level, than you cannot call yourself a basketball fan, plain and simple.
Say what you will about the refs (they have been terrible, I know), the Decision (the stupidest and most arrogant PR move in the history of sports), and his personality, on or off court (a bit of a whiner), but the bottom line is that he is putting on a historically good performance in these playoffs. This season for Lebron has not only been his best, but one of the best in the history of the league, no matter how you cut it. You don't have to like him, or root for him (I don't), but if you can't at least take a step back and say,
"Wow, he is doing some bleeping amazing things on the court right now."
Then you can't call yourself a basketball fan. How can you possible claim to like a sport and then shun it when it is played transcendentally?
