I would like tabs in #Logseq too but for now you can use the Tabbed Sidebar plugin, look at my screenshots here:
About organizing stuff, Logseq is definitely better than Obsidian, that is more a document editor + basic file manager.
In Logseq outliner UI you can organize everything you want hierarchically, even live queries, see the image:

In my experience #KDE is just as inclusive as anything else:
If you criticize the EU you are labeled as a "nationalist" and "far-right".
If you criticize vaccination obligations you are labeled as an "antivaxxer".
And so on.
Then you got banned with no right to appeal, just like everywhere else, just like in Middle Ages.
