Terrorism is about threats to "national security" and no way in the current culture would anyone think that women are important enough to have the elevated status of violence against them being an issue of national security.
Hate crimes are about where an act of violence is aggravated because the motive for that action is about "hate" prejudice against a protected characteristic.
And as we know society doesn't think women are as important to be protected as other characteristics (except also disability).
Sometimes it can seem that male violence against women in closer to genocide - please see definition of genocide:
Genocide is an internationally recognized crime where acts are committed with the intent to destroy, in whole or in part, a national, ethnic, racial, or religious group. These acts fall into five categories:
- Killing members of the group
- Causing serious bodily or mental harm to members of the group
- Deliberately inflicting on the group conditions of life calculated to bring about its physical destruction in whole or in part
- Imposing measures intended to prevent births within the group
- Forcibly transferring children of the group to another group
There are a number of other serious, violent crimes that do not fall under the specific definition of genocide. They include crimes against humanity, war crimes, ethnic cleansing, and mass killing.

But in terms of connotations, and the need to make it clear that this is about women as the target group, I think femicide is the best word.
Because it makes it absolutely clear it is about women. And for those still niggling on about TW, femicide would be covered by the SSE.
After all there would be no way of knowing if a TW was targetted whether it was because of presumed sex or gender re-assignment.
But all of these words mean nothing because what is being illustrated is that despite decades of campaigning about violence against women, society doesn't care.
Because it is society that is producing these violent men. They aren't recruited by manifestos online or in person. They exists because society forms them.
And not in any way want to diminish the sheer horror of what happened in that dance class, this is relatively rare, compared to DV.
For instance the recent murder of 3 adult women didn't lead to threads about VAW as being terrorism.
