Why do you, guys, think that is OK for them to rob me of 15 years of my life and make me loose my faith in God, and it is disrespectful for me to show them what I think about their lies?
If the person at your door who gives you the tract was personally responsible for your 15 lost years, I'd tend to agree with you.
Odds are, it's just some poor kid who doesn't want to be there, or someone who'd rather be fishing or baking cookies or whatever.
Your actions will merely upset him / her personally, or possibly even reinforce the idea that he / she is "in the truth" becasue of the "persecution" you are giving them.
Your anger is misplaced. The schmuck at the door didn't rob you of 15 years of life.
