Negativity affects me, but that shouldn't be a surprise, because it gets to any of us.
That's why, even if I like the writing style or the knowledge of some people here, if they keep spreading negativity, I start(ed) avoiding them.
Of course, as you mentioned as well @taskmaster4450, their posts are also read by new users, and maybe even by people outside Steem, and the negativity is spread and associated with Steem, many times blown out of proportions. That's a shame, given all the positive aspects of this ecosystem!
