They're just looking at it from their point of view. I don't think the people are uninformed, they're just not looking at it from your view point. Just enlighten them to other scenarios that aren't their own.
I commend you on this noble, idealistic viewpoint and agree, but it's usually* not very fruitful to try and enlighten others when they see the world from their own scenario.
This is why there are brand partisans (Nvidia, AMD, Intel, Apple, Google, ... take your pick) even in the tech world where you would think people would be a little more pragmatic (buy what suits your needs, recommend others choose what suits their needs) about matters.
This is why we have this forum and then two subforums specifically for AMD and Nvidia (which is where the other 1070 Ti thread is, for anyone who missed it). It's just easier for us to assume other people must be "stupid" for not liking what we like, or not making the same decisions we make, and this leads to uncivilized and unproductive debates and flaming.
Which is too bad, because honestly I wish we didn't have to split these threads over three forums. Anyway, my mini rant is over - back on topic.
* Still worth doing, just bear in mind there will be friction
