The person wanted to explain branching dialogue to an experienced game dev - coating it in politeness doesn't change the fact the person was trying to explain her job to her, something female devs especially have to deal with all the time. I don't know about you, but I've had to deal with people with no experience trying to tell me about my field of expertise before and it is rude. Full Stop. You wouldn't go to a mechanic and tell them how to fix a car cus you like cars, you wouldn't go to a doctor and tell them how to cure people cus you read a few articles, and you wouldn't tell a chef how to cook cus you like food. So the dev was a bit rude in response, but just cus the original commentater was polite in tone, didn't mean the message was actually polite.
