"
Accept
him whose faith is weak,
without passing judgment
on disputable matters.
  One man's faith allows him to eat everything, but another man, whose faith is weak, eats only vegetables.
  The man who eats everything must not look down on him who does not, and the man who does not eat everything must not condemn the man who does, for God has accepted him." - Romans 14:1-4

We need to stop comparing faith and theology and arguing about doctrine or trying to attempt to convince that our beliefs are stronger, better, or more correct than others.
  We can only be responsible for ourselves and sometimes I wish that people would quit worrying about each other and what other people are doing.
  It's not their place to do that.
  We can only worry about ourselves, we don't have the right to worry about anyone else!
 

I do think we should be there for each other and
correct,
rebuke and
encourage (2Tim 4:2b) each other, but not even that until we're in the place to do so – just one example: when we have that person's trust and that person knows that we're correcting or rebuking them because we love them and because we have their best interests at heart.
  Or when we know that
our heart is right in correcting them.

We gain that persons trust by truly loving them, serving them and listening to them.
  Until then, if someone is going to try to tell me not to do something or to believe this that or the other, I'm going to respond with rebellion and be like: "Who are you to tell me that?
  You don't even care about
me, what you’re doing comes across as you just wanting everyone to believe what you believe.
  And that's isn't love, so quit judging me please."

Because we are all responsible for ourselves, and accountable to God for everything we do we I feel like instead of worrying about everyone else’s bad lifestyles, we should be seeking to know Jesus more and more personally, and learning to care for what he cares about.
  If we are doing that
  I feel like everyone will be so much nicer and loving and careful about what they say to each other.
