No, nobody expects you to not read a guide. The thing some people take exception to are being called "unprepared" for not wanting to read a guide. They aren't wasting your time, just make groups where everyone is guided. People like to play blind because a lot of the time a guide will remove most if not all of the challenge from a battle. I'm not a hardcore blind player, if I come to a total loss as to what to do I will check a guide; and there have been plenty of times where I've done that and a battle has gone from being hard to being a breeze because the challenge was to figure out what you're supposed to do... actually doing that thing is easy, which makes the battle easy.
OFC, if you want your content to be easy thats fine, but calling players who want to be challenged unprepared is so far off base its unreal.
