I dunno. Which is worse? Both are pretty bad.
With the amount of damage done i'd say racism might be worse.
A career ending tackle would typically get 3 games though, and i'd say that is worse than racism, so i'm not sure logic applies when the FA dish out punishment
I've always thought that if a player is deemed to be at fault, he should sit out the length of the injury he causes. It might be the death of tackling, but I hate to see the beating Bale and others receive every week from planned, cynical fouling.
