How can we, with a straight face, argue to put females in a better position than males whilst also arguing that is downright unfair and unequal for males to ever be in a better position than females?
Why are you so insistent that "having a greater number of options to choose between" automatically translates to "is in a better position"?
Personally I don't think the choice between 'hot and uncomfortable' or 'horribly aware of own vulnerability at all times to the point I will and do self-exclude from society rather than choose this garment' is much of a choice.
In fact I think it's pretty similar to those poor schoolboys who could never really choose to wear a skirt lest they get laughed at or beaten up.
A skirt is not, according to you, an option for them.
A skirt is not an option for me either, for very similar reasons.
Yet they get shorts, so they can still be cool and comfortable.
But I don't. I have to wear trousers regardless of the temperature.
The two options you're giving boys allow them to meet both physical AND psychological needs.
The two options you're giving girls give many of us the option to meet one or the other need, but not both.
You're denying a subset of females the option of being cool and comfortable in summer - which as you already made clear is very very important for men.
If comfort in summer is so important, why are you in favour of giving the boys what they need while denying that same courtesy to girls?
You're giving the boys the better position and calling it equality.
