Sorry, I am male and a huge feminist - (see some of my other postings on here!) but I don't see the issue with this - if there is a minister for men that has no bearing on any other ministerial role - so I am not sure how it is or isn't related to their being a minister for women...
arguably you have a minister where there is a sizeable portfolio to deal with - there is absolute clarity in the value in having a minister for women - no-one needs spelling out all the various issues that can and should be tackled...
but none of those are impacted by or linked to having someone who deals with the sizeable portfolio of issues around men...
So, one doesn't affect the other.
But is it needed...
I think probably the answer is yes - there is a lot of evidence around mental health issues / crime stats / educational shortfall / etc. which would suggest that having someone with a portfolio which focused on solving some of those issues might generally be a positive for society not just the men / boys involved...
let us also consider it from a 'females perspective' would it be helpful to women if there were to be a focus on solutions for male mental health issues? we see a higher percentage of men getting into crime stats - is that worth focusing on?
nothing in society is isolated, but any minister's job is to raise society as a whole, from one specific angle - so having a men's minister is not about advocating for more pubs showing football / opportunities for MAMILs to ride around on bikes / promoting weird and wonderful hobbies which the wives can't discuss on mumsnet - it is to look at the same set of issues that impact us all, but from a specific angle - that should benefit all.
