I hate the term "Toxic positivity", sounds like some redditor/twittard leftie type bullshit and really just serves as code for "People don't act like I want them to". If you hate "le toxic positivity" then just screech louder, if nobody gives a shit then maybe just admit either your complaints are bullshit or nobody cares and its a waste of time.
Trying to incriminate people for not feeling or acting like you want is typical "I WILL MAKE IT YOUR BUSINESS" internet bs, if I don't care then I don't care, fuck off and deal with it.
