would it be right that it could be seen as akin to incitement to commit an offence?
“The home secretary has the power to exclude an individual if she considers that his or her presence in the UK is not conducive to the public good or if their exclusion is justified on public policy grounds.”
Generally in the past those powers have been used to keep people away from EDL demonstrations or from giving an assortment of right-wing / extremist speeches. The Home Office determined there was a risk of incitement to violence for permitting them in. In this case it's likely that the Home Office determined there was an unacceptable risk of incitement to violence against women, so he got shown the door.
Pretty much this, borderlining rape technique even.
