Gender bias on the internet

So earlier today, i was playing on the internet and came across one of those annoying adds. It was asking what type of job you want and right next to it had these little icons of characters playing those job roles. I realized that next the male dominated icons, was obviously a little male character. Like attourney, doctor, engineer, and cop. And next to the female gendered characters the jobs were nurse, assistant, and teacher. I just found it kind of funny that even on these little icons for jobs, it was being gender bias!
