My take on its, that these players signed a contract with the club,which stated that they they were willing to play in whatever Jersey's the club deemed necessary or desirable to me there are legal issues that sit around this..
It's a reflection on the cheater not their partner, same as rape isn't about sex or it's driver, it's about establishing power in the relationship, I wonder what the similarities between cheating & rape are hmm.
My experience is if a prospective partner doesn't like your taste in clothes, this is a big red flag, which has to be discussed and worked through before the relationship goes any further, because this is most likely to hide a multitude of issues that are likely to arise later in the relationship & cause real harm to each party.
