I think that even with a greater knowledge about anime we can't expect from them too much. Because even if they understand this beautiful world, why it make us to smile, laugh, cry,... We can't expect more than be consider like a movie fan living in an unreal world. Of course for normal people, fiction cannot be better than reality...
So even if they understand more our world we cannot avoid all the bad comments...
Two exemples:
why did you consider light yagami as a god and don't believe in god in real life?
why are you in love with nagisa furukawa in a visual novel and say no to julie who want to go out with you irl?

I'm sure you can find some exemples yourself in your own life
