Try and grab some sense kiddo.

the term 'martial arts' is pretty varied. Specifically i'm more interested in traditional japanese martial arts, more specifically sword arts. I know only really study kendo and iaijutsu.
I watch the odd MMA fight if i happen to flick to it on TV. I don't know all the rules... shock!
You like football? Do you watch every single match that you can or just your fave team?
Your 1st paragraph just shows your understanding is limited. It's not a problem, you simply don't think the same way. I find the passion that people put into following football quite surprising, but hey ho.
