Very true in my experience. Some of the meanest people I've ever known identify as "Christians." The nicest people ive ever met are covered in tattoos and piercings, while the most judgmental people ive met go to church every Sunday.
Don't be the one whose bitterness, smallness, and insecurities spill over into other peoples lives. Don't ever let others make you feel like a victim. Sensitivity and a big heart that is easily broken does not equal victim!
