Millar is possibly just as bad as Vino. I do like Millar though, as he does seem genuinely repentant. He could of course just be making it all up to get people to like him. However, he's a professional cyclist, not a professional actor.
There's been lots of stuff written about Millar and bearing in mind his nationality, we (or most of us) having English as our first language are more likely to read those things. I don't recall reading much said by Vino since he got busted (apart from his excuses), but he may have given his side of the story, but I've just never seen it.
Also, the English speaking (particularly British) cycling press were very hard on Millar and never had a good word to say about him after he got busted. Now they seem to love him and completely forgotten about it all.
I don't think Vino's nationality should have anything to do with it, but can understand why it may be raised.
I despise cheating of any sort - I can't stand it, but if the rules say he can ride again, then he can ride again.....
