..if church is a big part of your life, you might get the impression those who don't have that have a void in there lives where church should be..
Not all Christians go to church (Jesus said it's fine to stay home, Matt 6:6), especially if churches are full of crackpots like most are.
"Bad company corrupts good character" (1 Cor 15:33)
Some of my churchgoing mates used to introduce me to various churches years ago, but I soon got a reputation for walking out in disgust pretty quick.
That always amused my pals and they used to secretly place bets among themselves how long i'd last (5 mins, 10 mins, 15 mins etc), then they'd rofl when i got up without a word to anybody and walked out..
At a couple of churches i actually walked out before the service had even begun!
For example they took me to an Alpha Course once but didn't like what i saw, and walked straight back out. One of the AC tutors actually ran after me to try to persuade me to go back, it was like an 'Escape from Colditz' episode, but I managed to give him the slip down a side street and made a home run..
