I'm really not "spoiling for a fight". Not unless you just mean discussing. My opening gambit was to ask you why you held a view you'd expressed, and give what I felt was a counterexample. Is that really out-of-bounds?
There are a few different ideas here: i) should there be a men's minister (I don't have a strong view on this. Like you, I think it could do some good. I also think that additional layers of responsible ministers doesn't always help), ii) is the procedural parity argument persuasive?
I'm also not militant on that second one, but really interested in how strong the reaction from some posters is against it. Not just that it's unpersuasive, but that it's an affront ("Beyond belief", "pandering", "gtfu", "knuckle-dragging" etc., grounds to disqualify him from debate).
It's really not knuckle-dragging to say: "the argument for X is Y. Y also applies to this other situation Z, therefore maybe Y is an argument for Z too".
The argument for having a women's minister as a cross-government portfolio, is not just that there are serious issues to address, but that they are cross-cutting across portfolios. The MP's argument is that mens issues are likewise cross-cutting (e.g. suicide, abuse, your example of supporting positive masculinity, are not single-department issues).
That's not saying other issues that have cross-departmental ministers portfolios are unimportant or less important. It's odd, to me, to react as if it does mean that.
