An emotionally charged rant (what other kind is there?) is a projection. It can be good when you're overwhelmed and need to get through a crisis, but it's bad long term. That's how I see it, at least.
The same is true for being overly positive all the time: toxic positivity. It's fairly obvious to say that something is bad if it's all you do. There's no particular reason to single out rants here.
In fact, IME people who do that often tend to have an attitude than leans toward the toxic positivity side.
Experience? Lying to yourself only seems to make things worse? It can be agonizing, and you rob yourself of agency. I'm surprised this is not self-evident. How do you see projections affecting people long-term?
