It's simply my own opinion - those I've seen use it only use it when discussing a group of people rather than individuals.
I don't think anybody IS a snowflake

- after all, it's all down to the person using the derogatory term and what they consider to be a snowflake. One person's snowflake may not necessarily be another's. A bit like people calling others left-wing luvvies when it just means people who don't hold the same views or have the same attitude that they do. One person's left-wing luvvie is another person's right-wing nutjob. It all depends on where you yourself stand on the topic at hand.
I would imagine, back in the 60's and 70's when people were protesting the Vietnam and wanting to ban the bomb, others who didn't agree with them would have called them snowflakes. It all depends upon a person's point of view.
These are, obviously, my own personal impressions from what I read on here when the term snowflake is bandied about. I only really hear it on here.
