I wouldn't go as far and describe steemit as toxic. You should see some subreddits in comparison.
That being said, toxicity isn't necessarily a bad thing. Having some opposition, odds to overcome, a struggle to fight through is what makes an engaging story engaging. That is where real satisfaction can be found.
Oh yes, but to much of the reddit, facebook, style of drama is not good for steemit. Fortunately it only sometimes that things reach the toxic level.
