This is true. There are two kinds of people who would vote orange. There are those too dumb to understand that he’d make himself dictator, and consequently too dumb to use the Fediverse. Then, there are those smart enough to understand those things and evil enough to want a dictatorship, and they’re mostly on those tankie/fascist instances everyone else defederated. Neither of those groups will ever see this thread.
The fascists we’re talking about are strictly Trump and his followers. Other conservatives are also bad, but not bad enough to overthrow the government and install a dictator.
As for the argument that a vote for a third party is a vote for the bad guy, I’m not so sure. I voted against Biden in the primaries because we can do better. But when tens of millions of people are going to vote to install a dictator, the rest of us need to be united behind one candidate long enough to defeat them. Someday, third parties will be viable, but not this year.
