I actually think it's a bad idea. I adopted that attitude after a woman I knew got knocked down and kicked and called a (Greek Island name) for having a shortie mohawk.
Not because the haircut is a bad idea, hair is hair, but because people will judge you. You will find you are suddenly getting stopped by the police and being regarded differently by a great many people who used to like you. From someone who had a shaved head at one time and at another time had hair halfway down her calves, and at one time had a shaved head with a 2 foot long skinny braid that started off to one side on the back of my head.
People judge by appearance. That's the reality. Jobs, school, and on the street. Your mom a young person who had a mohawk herself? Probably a different attitude than your Grandmother or Grandfather, or someone hiring you for a job, or interviewing yolu to apply for a school. A nonconforming hair cut causes trouble, and you have to accept that some people are not going to like you and are not going to treat you right or fair, if you do it.
Mohawks are associated with amphetamine ('speed') and crank use. That's a fact of life. Some day they may just be a 'haircut' but today, mohawks change how a lot of people look at the wearer. It's considered to be a sign of a rebellious punk type nature, whether you have that sort of nature or not, people will assume you do. Out in the country and suburbs is different from being surrounded by admiring friends your age or, say a big city like New York where a naked shaved person wrapped in an American flag doesn't even draw a GLANCE on the subway....though she probably got some flack from her Mom and Dad when she went home...'what'ya DOIN' ta us! You're sucking the LIFE out of us!'
My suggestion? Color your hair, get an odd hair cut, but not something associated with amphetamines and crank. Not an 'arrest me' haircut. Bawk-bawk showed a hair cut that can be worked over to present to more conventional people, and brought out in all its glory for a night on the town with people who will appreciate it.
