I tend to be cautious rather than deal in absolutes, you cannot possibly know the motivation, you might be right, you may not. But declaring yourself right is the height of arrogance. The whole 'my opinion is correct', where is any evidence of this violent conduct from Son? Did he accrue a lot of red cards in the Bundesliga? Or is this another falsehood just conjured out of nothing? As far as I am aware that is his first red card for any kind of violent conduct in the PL. Again I may be wrong as I dont watch Spurs week in week out.
Even your argument about Spurs violent conduct doesnt hold water looking over the stats, we have accrued as many yellow cards as Spurs this season and we are equal third behind Arsenal and Watford. Ok so lets look at last season rather than just bias conjecture, hmmm nope, Spurs are 15th for yellow card accrual last season(56). Ok lets go back 2 seasons, hmm down in 18th(50). Not a lot of evidence here supporting your declarations to be honest.
The fact you don't even deign to even give credence to a lot of other factors brought up by other posters is telling. Nope 100% Son's fault.
Your whole argument revolves around that if Son didnt go flying in for the tactical foul the leg break would not have occurred. That is equally countered by saying, well if Aurier didnt stand on his foot/ankle the leg break would not have occurred. This is not a large leap of logic, would the leg break of happened with just Son flying in? No, Gomes was still running with Son on the ground behind him. Would it have happened with just Aurier? Again probably no. Both influenced the final outcome.
