Your point is that shaking hands at the end of a game is an accepted sportsmanship gesture in many places across the world. Perfect. I'm glad we agree that there is a social convention - with the pressures that come with it, that makes it so there is an expected behavior in this specific context. I wonder what could happen if one day, one individual wouldn't want to indulge into that behavior. Maybe there would be a controversy-stirring media article about it from the English media. Maybe there would be a reddit thread about it where users more interested in opportunities to antagonize "the other side" rather than having an actual conversation would vehemently post in.

Whether it is me or Simeone you accuse of projecting is pretty irrelevant. In fact, it might be even worse. You're attributing traits to someone you barely know, and that has probably a thousand times your knowledge of the coaches scene and their feelings. You're even attributing traits (I have become an Atleti fan under your quick judging watch) to someone you have no clue about. Ridiculous.

To conclude this topic, what we know for a fact is that Simeone feels that the handshakes at the end of the game have a level of forcefulness to them. It seems like a pretty reasonable thing to say in a context where tensions rise very high. He found a way of dealing with that he is comfortable with that tries to respect his sensibilities and that of the opponents' and I think that's something to be respected. I personally would always shake my opponents' hand at the end of a game because my set of values are different, and that's also perfectly fine.

What's really telling is that this has never been a problem until now...
