To me, both parties are guilty in some way of creating this elitist raid culture. I'm by no means a raid veteran, but neither am I a total noob and have been able to raid with some of the best of them without them even realizing it's my first time through a raid. I've been there though. I don't have the experience to lead my own raids smoothly and at the same time I feel other leaders are getting ridiculous/unreasonable with their expectations of other players. Leaders/Veterans, my suggestion is to ease up. Understand that not every other player will be up to your level but also that it doesn't have to be that way so long as your willing to be patient and teach others "the way" and of course be approachable. Newer players will be more receptive to you and long term, you'll have a larger pool of capable raiders to run with and improve the community overall. Newer players, my suggestion is to understand your limits and be honest about it. There are times where you need to let other people know that you don't understand so-and-so mechanic and it doesn't help you or your raid team for you to fumble and fail through it a dozen times when you could do it right the first or second time after asking about it. It's one thing to be ignorant about some aspect of the game, it's another to be obstinate and willfully ignorant of it. It wastes everyone's time and frankly it's rude. There are resources and guides out there to help you prepare and be an overall more effective player, take advantage of those and be open to becoming a better player.
