Brexit Poll and Impact of Early Colonialism ?

I am a fictional character but if history serves me well, Colonialism was not. It doesn't take much to confuse an old hoboclown detective like me but today's Brexit Poll presents an investigative puzzle. The question is whether the history of British colonialism argues against the Brexit Poll phenomenon ? Perhaps, you could read about it at the following site and tell me later what you think, https://en.wikipedia.org/wiki/Colonialism
