If people respect you, respect them back (cause they earned your respect).
If they disrespect you, disrespect them back (cause they don't deserve your respect).
They represent their (sick) ideology, you represent yours fighting back (a hope for a better future with less morons).
As Miyiagi would say: Whole life has a balance....
Balance is everything!! So, respecting A holes in your life will never give you balance and will never make this earth a better place.
