If someone is male and goes online claiming to be female and fighting for the right for men to access women's spaces and services then they can expect criticism from Exulansic and others.
If someone goes online and is honest and compassionate then I don't believe that they are at risk from Exulansic.
I believe that Exulansic's position is "sex is binary, keep all men / males out of women's spaces". I have zero problem with this. But it means defining men and women, which means defining male and female as male and female is sex, and men and women are sex classes.
Male or female is not something that is simply "penis or not?", and because of TRAs we can't simply say "it's obvious, we've worked it out for tens of thousands of years, why on earth would humans have suddenly lost their ability to correctly sex other humans?!?!?" It has to have a more definitive meaning - because of TRAs that definition has to get scientific. Because of TRAs trying to eliminate women's sex based rights and a tiny percentage of trans women passing reasonably well, people who are GC cannot simply say anymore "looks female, is woman".
I have zero problem with someone with a medically diagnosed DSD trying to make the case that some - a tiny tiny minority - of male people should be treated as if they were female by society. I don't know enough to know when that should happen, if at all.
Now to get a bit more specific and actually talk about AIS (having done some reading).
From what I can understand, AIS prevents normal male sexual development, and as a result, those presenting are XY. It would be weird if females were presenting at their doctors complaining that their female sexual development was not happening in a normal male way. I don't know if AIS cannot occur in XX people, or if it can occur but it is never noticed because it doesn't do harm to those on a female developmental pathway. I think that this is a question that Exulansic is unable to answer as well.
From what I can understand, people with PAIS (including, it appears, the name-changing man who was brought up as a boy and transitioned to presenting as a "woman" at 17 and who Exulansic was saying was male) have sexual characteristics which an ignorant person on the street might clumsily call "intersex". People with CAIS have sexual characteristics which an ignorant person on the street might clumsily describe as "female, but not working properly".
The problem we have is that when lots and lots of people who are categorically and unequivocally male with no DSD claim to be women on the basis of sexual characteristics such as wearing a dress or having breasts or not having a penis, then women are inevitably going to start saying "sorry, female characteristics are not good enough, we need a more definitive set of criteria", however well you pass. And that leads to academic debates where the search for truth is incompatible with protecting people's feelings.
It seems to me that there are two opposing point of view
(1) CAIS = XY = male = man, simple
and
(2) CAIS might equal XY but it also equals female appearance to the point that one has to start saying "if it looks like a duck and quacks like a duck, it's a duck".
It seems to me that in any normal compassionate society where there is a bit of give and take on all sides then viewpoint (2) wins.
In a nasty, weird society where man claim women's rights based on practically nothing then women are likely to start leaning towards viewpoint (1), because the moment you give an inch disingenuous activists and outright liars will start saying ludicrous things like "XY chromosomes give us no idea what sex someone is", and "this musclebound 6'4 weightlifter with a beard and a bit of lippy is a girl".
On reflection - and without necessarily seeing let alone remembering all of what Exulansic said - I think she should have made it clearer that whilst XY = man and no man can be a woman, and that DSDs have nothing to do with trans issues, there are a tiny minority of people with DSDs who deserve compassionate treatment by society that doesn't fall into the simple rules that work for the vast majority.
