There is vastly more toxic behaviour on Facebook, it's not even close.

If there's a severity to toxicity then perhaps 4chan can peak at a 9/10 whereas Facebook posts peak at a 7/10, but there's orders of magnitude more people posting on Facebook. If you pull in Facebook comment sections on news sites and consider those too, these threads where people publicly call for torture, rape and death, you realise that 4chan has an unearned bad reputation compared to the mainstream.
