Today there are folks who don't believe in the Big Bang and they get called heretics by the scientific establishment all the time... and there isn't a church person in sight.
Getting others to believe what you believe does make you feel better. Ask an Amway salesman. However, if you know the truth, getting others to see the truth is good...regardless of whether it's in line with your beliefs or not. Like... "there is a tidal wave coming"! If it's true then "thanks for sharing". If it's not true then you're a jerk looking for attention. Christ profoundly disagreed with the religious people of his day... even called them names... but never wavered from treating them with love. It's the Christian way... other faiths...not so much.
