I think if someone has a strong view on the moral repugnance of the activities of someone closely connected with Everton Football Club there is a duty to enlighten. it’s not a good look to come in here spouting off and then not providing back up material when questioned further.
It doesn’t need to be chapter and verse, just a few appropriate links to well respected journalistic articles will do. I don’t doubt there have been shady dealings, like I am in no doubt you could find shady dealings about every owner in the PL (or indeed Europe) where the owner has demonstrated morally questionable hard or soft power.
