It depends on how you define "snowflake". It's sort of like how I define folk music vs country music. If it fits in one of the two classes and I like it it's folk music if I don't like it it's country. Kodiak appears to be using a similar process between "snowflake" and "liberal". In regards to "poisoning the well" I'm not convinced it's a fallacy if the information is accurate and relevant. The first example may or may not be a fallacy depending on the facts of the case.
I don't love it because I'm rather ambivalent about it. Enjoyed playing it some when I was a kid and don't mind watching it too much if it's on TV but always feel that there's a better use for my time when I do. Problem here is people are trying to describe a multidimensional problem with only one dimension. I consider myself a conservative but there's a part of what is traditionally considered the right wing I've referred to for decades as "reactionary". They are characterized by a fanatic belief in their position and have elevated it to a religion if it wasn't in the first place. Their analog exists on the left and "snowflake" is a pretty mild term for them. Back to my first sentence to bring the point full circle are anarchist people so far to the left that they are on the right or so far to the right that they are on the left? If you deal in two or more dimensions it's easier to diagram unless the dimensions are non-Euclidean which they may be ....
