For the most part, we are all the same. However, when you throw in experience, the honeysuckle hits the fan. 10 people can be looking at the same sky, but if 1 person is colorblind and says it's green when the other 9 say it's blue, it could cause problems if none of them know what being color blind is or that it exists at all.
A rather simple example, but when you take into consideration that that's all this life really is, is perception, and that many of us place importance on certain perceptions ranging from simple preferences in taste of food all the way to opinions and beliefs that could mean life and death to us.
I do think there are certain people who get surrounded so to speak. It can be seen quite clearly all the time in the past and seemingly so in the present. In the past they would burn witches and heretics at the stake (one example of possibly hundreds of thousands). I mean it's really serious business. The best one can do is learn from mistakes and learn how to socialize with who and how and when. Unfortunately some of us learn the hard way and die from our mistakes and some of us just get lucky or had the sense to do things in all the best ways and live to prosper, and all ranges in between those two extremes.
