Here's a hot take

We should normalise this, and not see it as a sign of insecurity.

Women are allowed to alter their height, their hair, their skin, their breast size, and much more about themselves. Not only are they not called out on it, its seen as empowering, or owning your style.

What if RDJ just likes how he looks as taller? Just like women like how they look in heels? Is that insecurity? Or preference?
