I can understand where you are coming from Fitzy.
When Arsenal players act like Twits my first knee-jerk is to come up with excuses for them and try and play it down.
But to be fair it's real straw-clutching going on there... posting a pic of Chellini's past transgressions? Really?
On that logic it will be well justified for someone to proper murder Suarez next game out considering his transgressions?
Yeah there's some definitely straw-clutching going on, and I think anyone with half a brain isn't really debating his guilt anymore or trying to claim that Chellini's past transgressions are at all relevant. But your knee jerk reaction is a common one I think (generally, not in relation to the current Suarez thing).
People's moral compass seems to shift when it comes to football and sports in general. See Patrick's avatar for example, some will disagree but a lot seem to laught it off as a "classic Siggy moment" or that Kruse had it coming because he may or may not be a dick. Nobody would support that kind of behaviour in real life, and although nobody would actively advocate for it in football either, we're not as outraged when it's Siggy vs Kruse in football than they would be if it was Stranger A vs Stranger B in the street.
