I can’t really think of a reason for that as Reddit is hated somewhat equally by “both” sides of the spectrum. It’s just something I find interesting.
They just have their own instance and are defederated by some but not all, which is the best solution as it means they stick to their part of the fediverse instead of hijacking subs that weren’t right leaning in the first place.
Yeah, right-wingers flock to “safe-spaces” as much as the far-left does. Lemmy doesn’t have the tools to make a single community isolated like they could on Reddit, so they have to go to their own instances and end up defederated.
The main differences between left-wing and right-wing communities is that the right-wing ones quickly deteriorate towards a lot of hate related things. This leads them to being isolated from the rest. The left wingers are mostly tolerable and are just over zealous in preaching things like forcing everyone to use pronouns, lmao.
