I think you should read the rules.
FA rule book on what constitutes serious foul play and punishable by a red card.
Yeah, lets play the stupid game. Breathing is dangerous the air could be filled with toxic gas. There are levels of danger, players agree to a certain risk when they play football, the most dangerous types of tackles are punishable by red cards because you shouldn't do them. There is acceptable risk, and not, lunging tackles, two footed tackles and Nani's tackle the risk is because you are off the ground, in no control and the full weight of your body and all the momentum can go straight into the other player.
Where have I argued that everything should be outlawed? Where did I saw "normal" tackles have no danger, where did I saw it should be no contact, when did I bring up overhead kicks as being fine, no where, for any of these things.
You can tell when people have a point, when they argue against a point you didn't make, rather than the logical argument you did make that has no comeback to it.
