The question is ‘why did you start?’ Spelling is decided by democratic vote now? Well, that’s very Greek of you. Almost as many websites use molon lave so that argument is meaningless for both sides. Both spellings are acceptable. But I don’t have to change anything all I have to do is use the same transliteration as most Greeks do.
Sigh....
Because ever Greek - English letter chart I have ever seen looks like the chart above, B not V for Beta. And I have never seen "Molon Lave" until you posted it.
