There's...a lot wrong, here.
Your first three pics are from Cardcaptor Sakura and two different seasons of Precure. And they lack context.
>"I like you"
Tomo-chan is a creepy ass stalker who wants it on with her own cousin. Her mother was much the same before her love interest died of Japanese AIDS. CLAMP on a whole tends to sneak a lot of sick shit into their work you wouldn't catch even in a SJ comic, including the pedophilia (rika), the stalking (Tomo, Yue/Yukito), the May-September issues, the rampant incest tripping (Tsubasa Reservoir Chronicles), etc. Not actually somehting you want sinking into your daughter's brain to give her ideas.
Precure is less so, but you're off for different reasons there:
>Nagisa's love letters
She blatantly chases after dick for two seasons in an unrequited romance (Fuji-P). She doesn't do girls. In fact, aside of a scant few cases, there's no real lesbian action that goes past cotton candy level subtext. And mind, shoujo demographic stories seldom beat around a bush when they want to be blatant about relationship stuff (See also Sailor Moon, CCS, Shugo Chara, & hundreds of other titles).
>Mana staring at Makoto's poster
This one you can almost make a case for, but problem is it's the wrong characters. None of the girls outside of Regina, one of the villains, has anything approaching a crush/obsession with main character Mana Aida. And with Regina, it's very much an obsession.
Finally, that last pic is not a "targeted audience" information, it's the demographic that actually tunes into the Sunday morning Hero block for Precure and Kamen Rider. The older boys stick around because Precure isn't pastel garbage that a lot of people write it off as, and yes also because they're lewding the Cures. And the action sequences are mostly decent, though a far throw from the seasons of yesteryear, after the various PTA lobbyist got into Toei's ass about just how heavy and violent Heartcatch Precure was. But to the point, they script those shows to retain the audiences that tuned in to begin with.
tl;dr the lesyay is in your head, anon. Japan directors very seldom dance around such issues unless they're blatantly pandering for their audiences to pick up blurays.
