I switched my Twitter account back to protected, and I've decided to try to decrease and possibly stop my overall usage of Twitter.

There are too many Nazis on Twitter. I don't mean this metaphorically; I mean there are self-identified Nazis and white supremacists. Some of them are individuals. Some of the are companies, selling things like coffee. They feature Nazi slogans and logos on their profile, and they are proud of their beliefs.

I don't need to support a site that decides to platform Nazis. These are people who would like to see me, my friends, and my family dead. This is not hyperbole.
Maybe I'll drop in on Twitter here and there. This is not a hard- and fast-rule. But if you see me here instead of Twitter, their support of Nazis is the primary reason.
@Greenfield I did the same a while back, for the same reason. So far I do not miss Twitter.
