I like football
football is a team sport, it really requires a lot of varying degrees of kicking
That is true and that is the reason it is called association football
football can mean different things in different regions, football in the sense you are saying is called soccer in the US
You are right soccer is football. American football is different 
the different variations are called codes
Really? Which one of them do like playing or watching?
I am not a fan of most if I had to pick one it would be the NFL, before the protests, there are several variations in history
