Enough with this sanctimonious nonsense.
You know exactly why all of this is relevant, but I will spell it out since you are making a show of being so open minded your brain has fallen out.
All unknown males - all - are a potential risk to children, and should be treated as such until it can be determined that they are trustworthy. The rate of non-fathers harming the children of their female partners is astronomical. It is common for predatory men to target single mothers with the intention of harming their children.
KP has been with him for three weeks so he is still very, very much an unknown quantity.
The fact that he is gay is relevant because it calls into question his motives behind having relationship with a woman. It could be entirely innocent, such as that it’s a mutually beneficial arrangement for them both: he gets attention, possible free housing, and more views on his channel; she gets an ego-boost, column inches, possible sub-letting money. But it could also be sinister, as he now has unfettered access to a vulnerable young male who is utterly incapable of speaking up for himself. The former scenario is obviously far more likely, but the latter can’t be discounted, because Al is unknown. And the fact that his orientation is to males makes a sinister motivation somewhat more likely than if he were straight in this particular case (the opposite would be true if Harvey were a girl).
On to the porn: this is a smallish flat making privacy difficult. Harvey is known to have gone rampaging through the mansion, so how will he behave in a confined flat during lockdown?
Porn involves continuous re-takes until the scene looks good, therefore the sex goes on for far longer. Al sometimes films scenes with other men, raising questions about which other unknown sleazy men will be allowed into the flat.
(Additionally, the fact his scenes often involve anal raises concerns about biohazards).
Finally, there is nothing wrong with having concerns with the morals and judgement of those who make porn. Not everyone agrees with porn, and you are the one being judgemental towards those with a differing worldview to yourself.
We’re not talking about acquaintances, we’re talking about Harvey living with this man in 24 hour lockdown after knowing him for 3 weeks.
I hope this answers your questions and you stop throwing around accusations of isms and phobias.
My guess is a combination of sympathy-fishing and ineptness. If she is now living in a different county, she may not know where to start with getting him re-assessed for help under a different local authority. Every county is different and has different processes, all of them hard to understand.
