“Safe space” also doesn’t have to mean milquetoast or self-censoring. I’m new to this particular community, but I expect there are all manner of topics that any of us could discuss passionately without being jerks. Reading the description of the founding ethos of this community suggested only that I make a commitment to being decent and that I respect the dignity and celebrate the validity of others who aren’t like me. I don’t see anything in there about restricting vigorous discussions about tax policy or guns or whatever the day’s hot topic is as long as you’re decent about it and start from the assumption that people can disagree in good faith.
It’s hard to self-host right now, but Omnivore is a really, REALLY good project. I’ve actually retired my wallabag instance in favor of eventually moving to Omnivore (currently using the hosted version of Omnivore in the interim). And they are working on the self-hosting thing.
Plus side: the Omnivore iOS app (cannot speak to Android) has one of the best share sheets I’ve used, though right now it and the browser plugin don’t seem to be able to speak to self-hosted instances, though I haven’t tried that lately.
