Nowhere near? In absolute numbers you must mean, right? Because there are Fediverse instances that are completely dominated by all kinds of horrible hateful people. Merely looking at some instance blocklists is enough to feel the stench of the radioactive sludge pits of toxicity that are in this ecosystem. Facebook sucks but even its lacking moderation is still better than many instances on the Fediverse.

Of course, I don't want to invite the toxic people, though some might come regardless, but I don't think it's reasonable to just treat it like it's all toxic people. The good people who still use Facebook and Instagram also outnumber the entire Fediverse as well.
