This is true, but at the same time, your posts on let me don't get buried as easily. And the karma hear truly doesn't matter.
It's mildly frustrating that you can't post anything that's even remotely close to positive about any use of AI, or any positive information whatsoever about Tesla over SpaceX without being said that you're sucking musks cock. But in those respects the only thing different between Lemmy and Reddit is the number of people that will come to your defense, and of course in Reddit if no one comes to your defense your post is basically buried.
You're all so far less likely to have a reasonable post here removed. Yes it still happens, yes a few of the communities are still moderated by biased enough individuals to delete your content but it's much less prevalent than it was at reddit.
That said, yeah if you are mostly conservative you are going to have a very bad time trying to soapbox here
