I noticed Michael Foran's Twitter / Nitter page is down (probably temporarily), and I saw some of the women's rights Twixens discussing his view. There seems to be an (academic) debate about whether the current lawsuits and the academics, researchers and supporters are even going far enough.
There is a legal researcher called Alessandra Asteriti
https://nitter.poast.org/AlessandraAster/status/1951154857999843509#m
If you google her, you'll see she was a professor in Europe (and she says in UK, too), thus should know a few things about the law.
She's criticising Michael Foran in the above tweet, and in other posts on her timeline you can see also Helen Joyce and Maya Forstater being adressed.
Her main point is that the careful language about "gender critical belief" is still giving in to TRA and ceding the point that there are different beliefs, but in an area where the science is so clear, that you might as well discuss the earth being flat. Others are of course free to have different beliefs, but the main angle is how far this belief translates into laws that affect everyone else (I don't mean the psychological research about gender and sex, but the main point about sex as binary).
It's as if believing the earth is flat converts into hindering anyone from going more than 200km away from their home lest they fall over the edge.
The quote Asteriti reposted from Foran might be from a specific context, which I don't know. Thus I'm careful to judge that on its own. Additionally, anyone taking part in the discussion, giving the general political climate in the past decade, would be careful about what they say as an expert in public. I see this kind of language about "belief" as a step forward from before (esp. the Forstater case) and not as final conclusion. Foran was likely trying to avoid prejudice towards one group (rightly so) and focus on the legal side only.
Ms. Asteriti was mentioned in a thread a while ago, too, about repealing the GRA:
