Unfortunately you're right however this was different, the fact Holgate reacted out of character and touched the referee and then had to be held back by 3 Everton team mates tells you it was serious. Also Tom Davies ran on the pitch trying to defuse the situation, as if it was son of a bitch as the RS say. The referee obviously reported it to the 4th official, even the ultra pro RS BBC recognised it was probably racial. Nobody reacts that way to being called what the RS called him, nor do they try and get the attention of the referee. It's not like Holgate is a Cattermole figure always looking for a fight. The only other time I've seen players react like this was when Austria played Bosnia and Dragovic an Austrian player of Serbian heritage made some comment about Muslims to Besic and Dzeko heard it. I think he apologised afterwards, because he was just caught up in the moment so they didn't charge him. A black Arsenal mate of mine was the first one to tell mate about it saying he was surprised Firmino didn't get sent off.
