Thing is, the nature of abuse is that you tend to normalise it if you've been through it yourself as a way of coping with it and surviving.
The long and short of it is that most people being proper horrible cunts about players probably don't even realise they're doing it, because 'being a right horrible cunt' according to most people is perfectly normal according by them, hence why they do it. In order to acknowledge the shittiness of their behaviour will probably involve acknowledging that a lot of the ways they've been treated in also abusive - things which they have accepted as 'nornal' in order to cope with the pain of it, which understandably most people in these circumstances are not going to want to do. Too painful. Too much truth.
Honestly, telling people they're being verbally abusive, horrible cunts isn't usually going to work, even if it's factual by most people's standards.
What we need to do lads is galvanise and bring in any party that (a) invests in the direct services that work with child abuse (social services), and more broadly (b) works to eradicate poverty and therefore the multifarious stresses associated with it - stresses which, if a mixture of things come together in the right (wrong) way, result in parents not having the emotional energy or insight to relate to their kids in any kinds of empathic, nurturing way. That, in turn, creates the kind of culture whereby being a vile, abusive cunt can be seen as being somehow virtuous, ie 'telling it how it is'. That's how you deal with abuse - support people to bring up kids in a culture whereby they have enough support so that they have they have the emotional capacity to be empathetic and nurturing. Those kids will grow up not wanting to (a) abuse people in their life, or (b) abuse people who are not in their life, eg football players (or actors, or whoever else)
Another way of putting this is: Football is basically Corrie. It's fucking daft at the end of the day. It's just a way for us to keep ourselves occupied until we die. Any retard that treats it 100% seriously without any sense of irony needs to sort their fucking lives out. I've got family in hospital, we've got a lot of people using food banks, we have mental health services that do literally nothing right up until the point of someone trying to kill themselves - they'll literally do shit all up until that point, and often the only way you'll get seen anytime soon without paying £50 per hour for the privilege is to attempt to off yourself purely for that reason.
Point is, fuck off with your abuse. Sort out your trauma or get a sense of perspective or do whatever the fuck you need to do in order to place your following of a sports team in its proper category. That category is not life or death or nearly enough to justify verbally abusing people, either online or in person
