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.
I think the only real way for anyone to get it is to experience it. I thought it was bullshit propaganda too and I also thought I was relatively far left before first arriving at the .ml domain and further lemmygrad. I am still kind of surprised that we have a community out there that large that seems to legitimately identify with the 'tankie' ideology.
It's a bit of a culture shock realizing that you might just be a progressive moderate.
That's actually really good thing. In the U.S. not wanting to kill trans people makes you a "far left" person according to right-wingers. real "far left" people are pretty nuts, man. The vast majority of us are moderates who are now labeled as "far left" in the U.S. political discourse.
