Think about things from the point of view of someone who has never used Reddit or the fediverse, but you've heard about them both from recent news articles and want to see what they are about.
Reddit:- You Google Reddit and your first result is Reddit.com. You click the link and are presented with the front page. You from scroll from a few hours and end up signing up and staying.
Lemmy:- You Google Lemmy and your first result is a wiki article for Lemmy Kilmister... Your second result might be join-lemmy.org, which you're smart enough to realise it's probably more likely what the news is about.
You click join-lemmy.org and are presented with a page of information about the fediverse, links to set up a server and pictures of code...
There is very little chance you're going to investigate further.
If we want the fediverse to replace Reddit then either
A) Lemmy needs to improve its initial impression and Search engine optimization
B) We should be promoting a different platform with a better initial first impression.
I'd recommend kbin personally as it gives the same sort of experience as Reddit from the initial interaction.
It's fair to want to ostracize those who claim to be "moderate" who are anything but, absolutely. Concerning civil and political rights, there should BE no moderate. Either you support people's fundamental rights or you do not. Either you support everyone's right to love, sex, and associate with consenting adults or you do not. Either you support people's right to choose what to do with their bodies or you do not. There's little left to discuss.
Having said that, the US (and the world generally) has a terrible record, left or right, in supporting people's civil and political rights. I'm overjoyed that at least left leaning folk now support those rights, but it wasn't a decade or two ago that those on the left of the political spectrum were parroting many of the same things that the right now parrots. "Marriage is between a man and a woman." "Don't ask, don't tell." So while I am glad they've shifted, I'm always concerned that if the political winds shift again, those in power will sacrifice individual rights in the name of maintaining said power as they did before they decided that advocating for our rights was going to keep them elected.
"Moderate" doesn't necessarily mean centrist or unalienable, it's antithesis is extremist. Being moderate and supporting peoples rights to be who they are just means taking a more practical and slow approach.
You need both moderate and more extreme views of progressivism, otherwise you get drowned in either. They support each other, they don't necessarily oppose each other.
Moderate has taken a negative connotation in the US, alas, where it means "okay with hurting some people but not as many as THOSE folk." Moderation in approach, I can get behind depending on the issue.
