I might be part of your target, so I'll give an answer and try to appeal to you to be more open-minded because some of what you've said has a touch of running people down who don't play the same as you.
I really dislike this "if you haven't read a guide you are unprepared and haven't put the effort in" mentality. When content is created it's supposed to give us a challenge to overcome. The strategy is half of the challenge, executing on that strategy is the other half. If I've read a guide before taking on the content then I've had half of the challenge done for me. It's not about being lazy or not putting the effort in, if anything it takes more effort to learn on the fly than it does to have your hand held by others.
While some people might play games with the game on one screen, walkthrough on the other. Others want to play the content blind and figure stuff out for themselves. We should try to respect each other as much as possible with this stuff and if we are really rigid in expectations, then that's what statics and your FC are for. Heck, you can even create PF duties where players have to have cleared the content to join. You can get your easy run that way.
Talking more broadly, I've had people act inconsiderately in both guided and blind groups. I was in a blind friendly Ex group only last week where one of the players couldn't help but point out the strategy to a bunch of players who were trying to blind the content, then wondered why they got pissed off at him. This happens a lot, with players who have cleared content telling blind friendly groups the strategy.
Also, my first extreme was an experience. I was struggling to get a blind group together for a Ramuh Ex Synched group because everyone wanted a guide. So, I begrudgingly read the basics and entered a group. Informed the leader that I'd read the basics, was that OK? They said yes, and then accused me of lying because I didn't get the mechanics down in 3 runs. It turned out, even reading a guide isn't enough for some guided players, you need to more guide. Long story short, they'd been trying for a few hours and desperately wanted their clear. We went a few more runs, my connection went poor and they kicked me.
It knocked my confidence wholesale. The next day, I put together a blind synced no echo group myself and we cleared Ramuh in a few runs, then went on and did a load more. Turns out, it wasn't me who was the problem, and the guide wasn't helping them. So go figure.
Now, after having done a lot of Ex runs, I'm even more set in my ways. I will create blind friendly groups and we will clear the content that way. It seems to work pretty well and one things for sure, having read a guide or no has little bearing on whether you'll clear; and if anything, I find blind groups have more success than guided ones, and blind players tend to pick up mechanics more quickly than those who need guides. Thats obviously my own personal experience, but it seems pretty consistent.
So, yeah, just... respect that different people play differently to you; that both blind and guided players can be toxic, that both blind and guided players can be good or bad and if the group is good you'll get the clear either way. If you can't do that, then make clear on your PF description or use a static or your FC.
