People who come to a better environment from a worse one often do get "true religion", and I am sure that happened to a lot of Ruby devs.

You cite PHP. I would also cite Java devs whose first dynamic language was Ruby, and then went overboard.

Either way, enthusiasm combined with lack of perspective leads to annoyance for people who have that perspective, who realize that you're still missing some basic lessons. (Monkeypatching anyone?)
