I don't get it.
I am only about 5'6".
I don't have any anger issues.
I guess when I was younger, and more likely to be picked on for it, I'd get upset by it, but who doesn't?
Most of that was jr. high school type b.s. anyway.
FYI, I am the same size and weight as Jose Altuve, but he's seemed to do just a little bit better than I at his size and weight.
I am in shape, if you consider round as a shape.

@GrouchoTex Well,there is more to this equation than height. A lot of it has to do if you look harmless,most people looking to appear "badass" will leave you alone because in their minds there seems to be no "status" to scaring or beating into submission someone that seems harmless.
All during the 70's and 80's I had long hair and a beard,and rode custom Harley's I built myself. This was back when they were called "choppers". I could also do multiple repetition 430 lb dead lifts,which means I was fairly bulked up even though I didn't look strong enough to do that. Plus I took Shorin-Ryu for a little more than a year on Okinawa,and was usually alcohol-powered and didn't much care what I said to who once the words started flying.
I didn't go looking for trouble and was never rude to strangers on purpose,but for some reason a lot of people seemed to think the fact that I was alone meant I would bow to them instead of stand my ground. I learned early in life that if you did that,people would NEVER leave you alone,but that if you did a fair job of thumping their melon,people tended to leave you in peace. Wannabe bullies can live with being beaten by someone that looks like Arnold Schwarzenegger,but they know if they get beaten by a little guy THEY will become the target of bullies themselves.
Remember,a bully doesn't really want to fight,and most will go out of their way to avoid an actual fight. What they want to do is intimidate someone to the point they wet their pants so they can tell everybody how scary they are.
Hard to brag about being a "bad man" when you get your ass whipped in public by somebody 5'6".
I might get whipped,but I don't back down from anybody and I WILL draw blood and maybe break a bone or two before I go down. AND......,even then that doesn't mean it is over. If you started it and it takes a 68 Buick Electra 225 at 60 MPH to whip you,there will be a Buick in your future.
You don't have to do that but a time or two and wannabe bullies tend to leave you alone,and you can have fun and live a peaceful life. I had a highschool redneck I went to school with who was jealous because I was dating a girl he wanted to date,and he was constantly running his mouth at me,and then backing down when it started to get steamy. A couple of years later I am out getting drunk with friends the night before getting transferred to Okinawa for a minimum of 18 months,and he shows up sober,challenges me to a fight,and hits me from behind as we are walking to the rear of the bar. He then jumps on me and starts choking me. My friends dragged him off and ran him off,but I had to leave the next day.
2 years later I was back home on leave,and went looking for him. I didn't see him,but I guess somebody warned him I was coming and he decided to run away and hide,but was drunk and ran out in front of a car when he crossed the road. I wasn't even within 2 miles of him at the time. I was looking for him in another bar. I didn't even find out about it until a couple of days later when I asked someone if they had seen him or knew where he was.
People tend to leave you alone of they know there is a price to be paid,but you will never know a minutes of peace if you cower.
