My friend is trying to tell me that pronouncing Leonidas his own way (like in '300') is his opinion, after I've shown him several sources.
I show him several sources and he still wishes to believe the 300 way, it's just ignorance.
Here's the copy and paste of my message to him:
BTW
Λεωνίδης
LAY-OH-KNEE-DUSS
Or often LEE-ONI-DUSS

And here's a historical take on the Battle of Thermopylae, where people on the history channel say Leonidas a lot (includes footage from Rome Total War for dramatic purposes)

(Used sources on Google to verify how to pronounce his name.)
And I must add, even if his way is correct, he still fails to see any amount of proof in my sources I gave, and just blatantly ignores them.
