Only dudes that don't know jack about fighting and the chick that only cares about the jonas brothers concert she's about to go to would think something like that.
Height has zero to do with appearing strong, confident and authoritative. You'd be surprised how many super tall guys I've known that are complete lazy video game dungeon and dragon nerds that couldn't assert themselves enough to ask for fresh fries at mickey Ds.
Confident alpha male mindset comes from the inside. Any woman that's worth her salt and has seen people like struve get knocked dead by fatboys like nelsom and hunt/knows something about fighting/actually does mma herself would realize that the tallest man in the room isn't always the bigger man.
When I was a teenager I used to hang with this kid whose uncle was an ex marine with confirmed kills, and was a mma fighter in his spare time. Had several years of muay, plus a black belt in bjj and judo. He wasn't a single hair over 5'8", and would wax guys twice his size. We would go downtown all the time and he'd take us all out to eat at all the "cool" places where you see super fine chicks and big dudes.
There were always big 6'4"+ guys to go around. Believe me, her eyes weren't wandering to those dudes. Those panties went home wet every night because she knew that if any of those dudes disrespected her, her 5'8" man could and would turn their faces into silly putty and break their limbs in short order. She knew who was really the tallest in the room.
They are still together.
