Yeah, Toei, girls can wear blue, and you really need to stop littering history with the fallacy that boys can't wear yellow!! Wait, what?
Absolutely yes. They should have a female ranger too.
eh, you'd be surprised with some of the little boys here. I've read on a few Japanese parents' blog saying their son likes one of the heroines (most of the time it's Yellow) so much and only bothers looking at her. as for a Male Pink... urgh, still can't imagine it.
I don't want to sound sexist or anything, but I just can't see guys wearing pink spandex on Super Sentai. And you can go to any of your local clothing store and check out the men's section, and count how many pink shirts or outfits you can find. I'd be willing to bet that you won't be able to find any, if at all. On the other hand, Victoria's Secret has a "Pink" section in their store. I think it's nice to see that in Gokaiger vs Gavan movie, they have an all-pink Gokai Change, but to actually make a pink ranger in a sentai series would be rather far-fetch.
Unfortunately, there's still the stigma about the color pink, and of how it's a girly color. Boys who wear pink are labeled "pansies", and will get beat up. That's why seeing a male pink in Super Sentai is unlikely (though Marvelous is bound to change that).
On the other hand, Victoria's Secret has a "Pink" section in their store.
In that case wouldn't it be easier to just do away with Pink Rangers? Even female Pinks don't seem to sell as well as female Yellows or Blues, and there are other colours than pink to use in a lineup
