1 plus 1 will always and forever equal 2 no matter the opinion or circumstance.
Somethings really aren't that complicated.
Just because a person wants to believe something, that doesn't make it true. With basic common sense, which is extremely rare these days, and simple logic, you can figure most things out.
Of course, plenty of folks will argue and fight to convince themselves that the hand they are holding in front of their face isn't actually there.
But,
Is that hand still there?
Of course it is, and it never left. They just chose not to see it.
It really is just that simple.
