I think, by myself included, X's posts are being misinterpreted as defending Suarez's actions. It seems more so that you're trying to suggest there is something flawed with the value system of FIFA if they consider this worse than intentional violent behaviour on the pitch that can (and in the past, has) end a career or cripple someone?
This cannot really be argued.
However, I would say that it is more a case of FIFA finally getting a punishment right in terms of strictness, and we should ignore its correlation to other actions and behaviours. Look at it as its own specific form of behaviour, and punish accordingly, which it seems they did. And now they need to work towards dealing with actual injurious violence on the pitch in a proper fashion.
