Why form a culture out of church going?

i mean it may just be how my experiences with churches have colored my views, but it seems to me church goers gather there to socialize, try to one up each other on seeming more devout, and who can wear the best clothes, sit through a few hours of talking with the occasional bored song or two(no one ever seemed to get into it except at this one tiny baptist church that i went to, which believe it or not i still occasionally show up because i love the people there), which is why when i was a christian i used to make a habit of defying church culture because i felt it was more important to focus on the lessons than dressing up or socializing, because i always felt it was gods house and he would love all even the most poor downtrodden men, believe it or not i learned a few good lessons from being a christian, about self sacrifice for the greater good and being humble when others are not oddly enough by doing the opposite of what others did in church, so even though most christians dont believe in ex-christians, i am one i just moved beyond the need of belief(and fear of) a deity to have compassion towards my fellow man, i learned the few good lessons contained in the bible without absorbing all the hatred and judgement it contained... i know many people may not like me for saying that, but it is true once you read it objectively. the main reason i moved beyond Christianity is because there is no evidence, and i choose to say "i see no evidence for these claims" rather than lie to myself claim to know without a doubt that any deity exists and be intellectually dishonest, i just cant do that. so why form a culture out of it
