Yes, it does.
No, it doesn't.
I believe people should be matured enough to differentiate between recognising a person's talent and personality.
Of course, if the person has a poor personality or poor attitude towards you, it definitely is harder to publicly praise that person.
However, talent would remain raw without a positive or powerful personality and attitude. Therefore, I feel that personality is a crucial factor for talent to develop well and flourish.

Deny is the wrong word. Not appreciate is a better way of putting it.
