I do not know whether or not you'll be insulting god if you insult others. What I know is that, you who are full of sin yourself do not have the right to judge others, and what I believe from others fallback is that there is their inner strength that develops from it (Similar to how failure is the mother of all success). Finding out what that inner beauty is..... is what will provide you with TRUST which will lead to LOYALTY which will ultimately give you HAPPINESS. That is what defines 1 life, 1 girl, 1 death!
