One of the things that I like about Medium is the way they handle blocking. When you get blocked, the other person disappears. This is how we handle blocking on nderground as well.
Last time I checked, I was blocked by Holly Wood. I assume that she got annoyed at my responses that suggested that the younger generations are not going to be much different than the older (Boomer) generation. Blocking someone because you find them annoying is a perfectly reasonable response.
I don’t argue with Trump supporters. I’ve found that we live in different realities. Arguing with them does no good, since their reality is either fact free or racist (in my view). So I pretty much block all Trump supporters. After what they did to my country, I don’t want to read what they write.
Medium or nderground style blocking helps maintain better social interaction, since tends to reduce flame wars.
