Hating a player because he does something that hurts the club you support is rational (at some level) and cognitively consistent.
Hating a player, regardless of what he is doing now, who once did something that hurt your club is neither rational nor cognitively consistent.
It's just juvenile and pathetic. Did you hate Sol Campbell and refuse to celebrate our unbeaten season because he was once Spurs?
Rational? Certainly not. But consistent, absolutely.
If the way we both claim to feel about Spurs and its players throughout the year is to mean anything at all, I don't see how you cannot feel even slightly emotionally compromised by supporting an England team comprising so many of them.
