Athleticism and fitness are different, though.  I know a lot of wildly uncoordinated endurance athletes with exceptional fitness. 

That's called "moral hazard": a very cool name for a very important concept.

Actually even people's lack of fitness affect you, in the socialised medicine of Western countries the collectivity pays for people who don't take care of themselves. While intentions are certainly good, it creates incentives that make the system doomed to ruin

Good thoughts. I hope the elaborations in the follow up posts make those questions clearer. 

Your instinct on 15 might be a good starting point for me. I also might not have conveyed the point very well.

Undisciplined

Why would we discuss semantics of words? Lets leave it to linguistics researchers. It so weird that frequently people argue over semantics of words, instead of actually discussing underlying issues.

Why would that be relevant? Those are independent things. If one is not a collectivists it doesn't stop other people from being collectivists.

> 13. Since libertarians are not collectivists, shouldn't we stop complaining about how "the media" or other collectives are "acting"?

> 15. Similar to how a professional athlete doesn't despair for humanity's lack of athleticism, should libertarians go a little easier on people for not being at our level of understanding the depravities of the state?

Incorrect comparison. 
* Other peoples lack of athleticism **doesn't affect you**. That's why processional athletes don't bothers.
* Other people political decisions **do affect you**. That's why people do bother about spreading their political views.
