I'm fine with showing some emotion. But there have to be some limits. Righi and Evans was a bit of six-of-one, half-a-dozen of the other. But should Gesink really get headbutted for that?
Eric Cantona was 'showing some emotion' when he dropkicked that Crystal Palace fan. Inzamam-ul-Haq was 'showing some emotion' when he attacked those Indian fans with the cricket bat. You can apologise afterwards but it's still out of line to do that.
The problem for Evans is that part of what makes him react like that is how highly-strung and competitive he is, and that's also a key part of what makes him a great rider, so he can't get rid of that.
edit - and the only thing I'm 'coming after you' for is using the possessive pronoun 'your' as a contraction for 'you are'. This is your first language, and the foreigners here are schooling you. I don't mean to be the grammar police (actually, I do) but this particular error is a particular bugbear of mine. Just like when people write "Piti" when that's just a common typo for "a particularly upstanding, fine, decent, clean-cut young man from Murcia with a fine and totally natural head of hair".
edit of edit - yes, I do recognise the irony of that statement, even though it's intended as a joke, when I have an avatar with 'Piti' clearly transcribed in it.
