* "but then end up" -> "yet ending up"
Earlier part was written as "claiming to be", so the logical outcome
would be "ending up" instead of "end up".
"but then" is replaced with "yet" to make the text less repetitive with
"then".
* "But then" -> "After that"
Make "then" less redundant.
* "libtertarian" -> "libertarian"
Clearly a typo.
* "if their claims actually match reality or not" ->
"whether their claims actually match reality"
Paraphrasing, nothing serious here.
