I honestly think it was a bit of both.
And whilst I agree that SWs have a thankless, exhausting task, and it's not a job I would want for love nor money, I think that 'heart emoji-ing" messages to clients is totally unprofessional. I've said it before - there is a tendency for some women to infantilise gay men for some reason. Don't ask me why, but the over-dramatic individuals like JV just play into this stereotype and get a free pass for a lot of things. The ones who act like grown-ups (which is the vast majority) tend to be treated that way.
I think that this particular SW really should have been aware of her biases (we all have them) so that she knew to think twice when she encountered a situation that played into them. I daresay she will now - but it's too late for Preston.
Also, the subconscious ever present awareness that men as a social class are able to hurt us physically and sexually, is sometimes overridden those blokes are gay. The relief that they’ll not adhere to ‘average’ male behaviours when it comes to our perception of risk of sexual harm towards us as women can swing into that infantilisation and some othering.
It’s observable in women (as a generalisation) changing behaviour eg having no qualms about sharing a bed/room/getting undressed with their gay mate as he’s not going to be a creepy fucker like your straight male friend.
Because women and girls are always risk assessing their actions when it comes to men and changing their everyday lives and routines to accommodate this (don’t go down that dark street cos there’s a man there, sitting near to another woman on an empty train carriage away from the gang of pissed blokes, refusing a lift home from a male stranger etc) we’re probably just fucking relieved to have a tiny bit of time in the company of males who don’t seem predatory.
What this can do is lower our perception of safety when it comes to other male behaviours. We’re just so fucking relieved that we’re not going to be raped by this lovely chap who has no desire to ever fuck a woman and therefore include him in our ‘low risk’ group ascribed to women and girls.
Our species relies on making judgements and assessing risks. It’s not a moral issue when it comes to ancient inbuilt instincts like women being able to correctly sex a person from a distant by observing their gait/proportions/physicality. Women have a near perfect accuracy as opposed to men cos it’s based on evolutionary survival.
