I honestly don't know if this is a rant, or your talking to someone on here, but as for my opinion...
No, minding your own business is not being fake or selfish. There are somethings we avoid either because we can't answer it, or it conflicts a choice between two or more people you know and love, etc...
We're human, we don't always have an answer for everything. We as physical beings are flawed, but its natural. Those who strive for perfection are only following the destruction of themselves. To accept that your flawed, and still love who you are is wisdom.
