What insult?
I know you think you’re trying to be helpful, but I’m clearly frustrated by the difficulty level and your comment was inappropriate.
Telling someone the game isn’t difficult, when it clearly is (and is intended to be) is rude. It’s like telling someone to calm down when they are stressed out. It doesn’t work and it’s not helpful. It’s rude and condescending.
If you want to be helpful , post guides, gives tips, and be curious.
