This logic is so weird to me.
"Employees get insulted all the time, it's common as muck in employment, but the majority are mature enough to ignore it and go about their business in a professional manner. This one responded like an idiot (shouted swear words) and received an equally idiotic response from the customer. (bottle thrown at him)"
"Black players get abused all the time, it's common as muck in football, but the majority are mature enough to ignore it and go about their business in a professional manner. This one responded like an idiot (shouted swear words) and received an equally idiotic response from the crowd. (bottle thrown at him)"
"Women get harassed all the time, it's common as muck in life, but the majority are mature enough to ignore it and go about their business in a professional manner. She responded like an idiot (shouted swear words) and received an equally idiotic response from him. (bottle thrown at her)"
Feel free to say "that's ridiculous, it's a different situation" even though it's really just a matter being accustomed to it, not of it being in any way acceptable. If any of you were Di Maria you'd happily verbally retaliate for the abuse as well if you contributed to the potentially winning goal.
I mean hate him all you want for being a prick in general, which it definitely seems like he is. But it's not hard to see why he responded this way today imo.
