I am not sure of an instance that calls itself right leaning or nationalist given that the feddiverse is generally very left leaning. The only thing I can think of is Truth, but no one ferderates with them.
Or a comm that does this for posts on reddit or twitter? Curious
right wing usually do it on tradional MSM, and social media. social media has the right wing grifters, and most of them are on reddit anyways, they should stay there. the last thing lemmy needs is having conservative come here in droves while we still have tankie problem.
