It's plastered all over painted blocks of wood for $40 at mildly up-scale places (or places trying to appear up scale), along with other "gems" of wisdom.
It's not so much the cornyness, but the posh posturing and sheer stupidity of having vapid expressions on expensive blocks of wood.
It reeks of toxic positivity, its associated with privileged, usually white, usually christian, suburban and boomer wives/moms who get to sit around at home all day, in a home, whilst doing nothing, who often admonish their own children for not being positive and grateful enough, and also invent tons of problems about meaningless bs, while said children have worked far harder than they have, and are more educated than them, but will likely never own a home.
Every time I see the phrase "toxic positivity" my first instinct to contest it, because my first experiences with the phrase were a misapplication (that being positive is somehow toxic,) but so far on Lemmy, I've only seen it used in ways that make sense (the toxic expectation that others will be exclusively positive.)
In a lot of uh, fast food social media (Insta, Tiktok, Twitter) 'toxic positivity' is basically used anytime anyone commits a single offense of being too optimistic or endearing in a way that gives someone an instant knee jerk 'ick' or something, when they're in a bad mood and just wanted someone to also be as angry or depressed as them, in the moment.
...People who do not have narcissistic personality disorder understand that there's a bit more to it than that, namely long, established, continuous patterns in someone's behavior which indicate that this person has an enormous amount of privilege, does not realize this, to the point that they become blind to serious concerns and problems, and then those problems become worse and worse because of the toxicly positive person's nonsensical advice being detrimental and time wasting, or just vapid meaningless platitudes.
And then also, the privileged person often become overwhelmed when anyone lays out the basic facts of their reality compared to the privileged person, and then also they usually then get angry with the less privileged person for pointing this out, and now its your fault that you made me feel bad.
This can also happen at a large scale, where an entire organization or group acts like this.
Anyways, I don't see why this has to be a matter of high privilege vs. low privilege. There's definitely a correlation, but depressed rich people and happy poor people aren't uncommon. Also, not all questions of positivity vs. negativity are in contexts that relate to privilege. It could be about the direction of a media series, for example, which is where I've heard it misused.
You absolutely could be toxicly positive from a position of basically 0 privilege, such as maybe an ascetic who thinks that the solution to the problems of poverty is to actually embrace or accept suffering, and not do anything to change it.
We do seem to agree though that toxic positivity is a persistent attitude and mindset, at least.
There is a trend of home decorating which prominently involves plastering one's home with signage written in cursive fonts, with a prominent one reading "Live, Laugh, Love." Other common ones are "Gather" or "Coffee" etc. It's a symptom of stage IV basic bitchery and/or karenism.

There was a family that lived next to my parents that lost their house in the 08 crash because they were sold a shitty loan. They were the sweetest people. I happened to be visiting when they had a huge blowout family party on their last day there. I was hoping it was using the money that was supposed to go to the banks. They were the epitome of what I think the original intent was of that saying. The world sucks, fr, but you have to live anyway. It's not toxic positivity if you live it. That's my take anyway.
