The Asian woman on the original $100 Canadian bank note may have perpetuated a stereotype, but she still stood as image for an under-represented minority in Canada. In order to have properly fixed the issue, the stereotypical woman still should have been replaced but with a woman who is also Asian instead of a Caucasian woman. Doing so not only does not address the original problem in a healthy manner, but also continues the erasure of other types of people in Canada.
Yes, it may seem that portraying an Asian woman on a $100 bank note is a stereotype representation. Other ethnicities should be portrayed as excelling at medical innovation. A Caucasian woman is someone most Canadians can relate to. It is more neutral in terms of cultural affiliation. Dr. Emily Stowe was the first female physician to practice in Canada - after a long fight. Perhaps it is more historically accurate to portray a Caucasian women. Couldn't more than one image may be used in the future involving either gender.
It is fascinating that out of all the problems in this world the race of the woman on the $100 Canadian banknote seems to preoccupy the mind of many regressive leftists. If there are race restrictions in our society on who can wear a lab coat, especially in a male belief artistic setting, then there is a fundamental problem.
Everybody wants to change stuff and every time it is met with controversy. The only reason to change something is if it is blatantly offensive. If it is then that thing needs to be changed or taken down. It is a simple fact that you can not please everyone in this world.
