I think insisting on women being different from men is missing the point big time. (And fails to acknowledge that this magazine is hateful of men and women alike, and mocking anyone who is not hetero)
With regards to DV - that gets milder punishments no matter whether the perpetrator is male or female (and yes I'm aware, that the vast majority of reported cases is male perpetrator female victim). So whilst DV is a problem that needs addressing, I think that's less to do with women being marginalised than you claim.
Being divisive and insisting on women being a seperate group which needs special treatment isn't helpful.
The characteristics that are protected by the Equality Act 2010 are:
age (in employment, further and higher education only)
disability
gender identity and gender reassignment
marriage or civil partnership (in employment only)
pregnancy and maternity
race
religion or belief
sex
sexual orientation.
I think going any further than that would achieve the opposite of equality
