"it's rather sad that I'm a lone voice in the defence of men and boys, but hardly surprising, given that they don't count."
You aren't a lone voice.
I'm 100% in defence of men and boys, why wouldn't I be? I have a son, a husband, a brother, a dad, uncles, granddads, male cousins and male friends. Why wouldn't I defend them?
Saying that they have a generally easier life than my mother, my aunts, my nans, my female cousins and my female friends isn't the same as saying their life is easy.
I want everyone to be treated equally, have equal opportunities, and be free to be comfortable in their own skin.
Most feminist principles will help with that. Yes, even the men, shifting the balance further towards equality wont make life worse for the men. In fact it will probably make it better.
Equality would mean that my husband would be in a better position to do childcare (financially and socially). Equality would mean my son wouldn't be brought up with society telling him that there are things for boys and things for girls.
Denying that more men sexually assault women won't help either gender.
Denying that men, on the whole, are in a more privileged position won't help either gender.
We owe honesty to both genders.
