Why do people give each other thumbs down on religious questions?

Because everyone has their own opinion when it comes to religion. I believe in Jesus. I always will. Some others don't believe. And honesty, I'm okay with that. My parents are atheist and they always told they would respect my religion if I respect theirs. I come to realize I need to respect others too. Some people are so headstrong and only believe that others should believe what they believe. That's the world for you. In the end, I respect your religion and I hope you respect mine. Best of luck to you! :)
