Actually you're onto something really helpful here: "Worldly" people are the best source of normal feedback on how crudely judgmental JWs are. We can be so accustomed to the JWs smug view of everything that it's like a breath of fresh when people who don't know much about JWs give instant feedback on the JWs petty-mindedness.
I also agree with the other posters: Be more sparing in what you feel compelled to tell these petty-minded people because you know full well they won't understand. refuse to play the "Explain Game". Your life and your choices are yours, not theirs. Period.
