I've been reading a few threads recently, in which people discuss rather everyday type problems, usually involving poor or inappropriate behavior by one or more people, but nothing dramatically awful or unforgivable...
And so many posters seem to respond to these scenarios with such judgemental, angry, and unforgiving attitudes. Their anger may be directed at the OP, or at the person/people the Op is complaining about. In the latter case, they may at least feel they are being supportive, but often the tone is so unpleasant and toxic.
People I know - friends and acquaintances - don't generally express opinions like this. It makes me wonder whether people's private thoughts are more harsh and unkind than they let on publically - or is it just that bad-tempered people are more likely to post?
