I used to think parasocial relationships were inherently unhealthy, but I don't think that so much any more.
They can be quite comforting, especially when you don't have as much opportunity to build two-way social interactions.
I do think it's important to recognise parasociality for what it is, & not have expectations or entitlement about what the public figure is supposed to do for their audience.
It's also not great when mutual relationships get deprioritised in favour of parasocial ones.
