Why is this meantality ok in normals?

I'm getting real sick of this shit, its annoying watching your midlane die in an honest mistake, then they constantly keep running to the opponent and trying the same method that got them killed before, as if it was going to magically work this time. After they feed for like 3 times, you get this stupid message

"Its just normal's it doesn't matter anyway"

This is by far the most stupidest type of mentality, who cares if its normal's or ranked. The behavior that you display in normal's is the exact same shit you'll do in ranked if you cant effectively "practice and polish" your skills in a normal, you think your just gonna show out in ranked?

You think people play sports without practices? You think faker was just born making everyone else looking like shit without playing a shit ton of normal's?

Sorry had to rant, after being held hostage by a troll duo..
