No. People don't respond to calling them names, such as "snowflake". You think someone is called effete or snowflake and they think, "Oh, I feel so ashamed. That anonymous person whom I will never meet, has just nailed who I am. I need to learn a lesson from them and be humble and tough, not effete and a snowflake."
No. People don't give a rip what they are called other than to make them pissed off. Instead, the only person walking away feeling better about themselves is the name caller. True? When you call people names online, doesn't if feel good? Doesn't it give you a sense of satisfaction even if the person you label doesn't give a s***?
