Unfortunately, the UK does not need to import transphobia from anywhere. The UK's TERFs pioneered modern transphobia in many cases and they have been at it for a loooooong time. In many cases, it was the UK's TERFs who came up with a ton of the now common transphobic arguments which the US and other places adopted from them, rather than the other way around.

Mind, they are 110% fascists and they love to sit down with the US' Heritage Foundation and other fascist US orgs in order to coordinate with them.
