You can have fun on the street. (Most) everybody speeds sometimes.
There are times when the rider's risk taking is calculated, and times when that risk taking is emotion driven, or when the rider fails to use ANY risk calculation. In these scenarios, the rider's fun can put other innocents at increased risk.
Many of us ride spiritedly on the streets. We do so in a way where we endeavor to not place others at risk. The people down talking you have judged that, by your description, your risk taking is excessive and fails to properly balance risk v reward.
Also, they determine that, based on your own description of your skills and your actions, your own self-judgment is flawed, so many of your 'reasons' or excuses, in their mind, are baseless, leaving you as:
A person riding a fast bike that can perform above your skill level
A person riding an expensive bike without the financial means to maintain it
A person riding an expensive bike without the financial means to protect yourself with quality gear
A person riding a dangerous machine without the mental capacity to reduce risk when reasonable
It is because of these 4 factors that those who label you 'Squid' do so.
Never ride faster than you can stop
