Can you clearly and lucidly explain in your own words what you think "fascism" is, and why it applies here?
If you can explain why someone might think Trump is fascist.
What has Trump got to do with this? As far as I am aware, he's not an open-source developer.
It will explain to me your thought process and why you might think completely controlling a community, down to the type of personal projects posted, isn't considered fascist. Especially when the community wasn't asked.
Private property isn't a fascist concept. Unless you can prove that the United States government is using Reddit as a corollary for consolidating power, Reddit moderators aren't behaving in a fascist manner here.
