Summary:
“I don’t want all that church stuff.  I just want to live a ‘good’ life.  If I am basically a good person, God should accept me like that.  Besides, church people are mostly hypocrites”.

The core problem with those thoughts: You are saying “my values” are the “right values.”  Recognize that is what everyone else is doing — including “those people.”

A little more:

• Your values makes sense for the background in which you were raised and live.  It makes sense for the people with whom you spend time.  But that is also true for others that have different values from you.
• You are comparing your values to others instead of to God’s values.
• Yes, all Christians are imperfect and some have an ego.  But, in God’s eyes, the same is true of you
• You know that you have an ego because you think you are good enough and that you are better than “those people”.
• You think it is about being “good enough”, but that is not how God (or any good parent) decides whether they love their children.

Church is a place that imperfect people get together to compare notes on what God is actually telling us.  Unfortunately, many churches put their social, political or other values above God’s values … like you do…  Also, like you, many Christians judge others based on what they do wrong according their values and forgive themselves when they do wrong.  That is not how God looks at people.

Churches, and the people that attend them, are definitely imperfect.  But so are all doctors, mechanics and home contractors.  But, instead of just saying that I will not have anything to do with these people, you take the time to research and figure out who is really getting it right.  Then you go to those people and ask for advice because you know that they know more than you in an area.  Don’t judge God by His imperfect children, judge by what He says.
Remember that if God only allowed people God decided are good enough to be in the church, no one, including you, would be there.

Parents don’t decide to accept their children if they are “basically good people” and neither does God.  By saying you don’t need church (again, finding the right one takes work), you are saying that you know more than God and that is the root problem that keeps people out Heaven.

God says this time on earth is a time for us to figure out we are imperfect and look to Him — our loving and wise parent.  He says that He gives us a lifetime to figure that out.  But He also says there will a time when the line will be drawn.  Ignoring Him will not change the outcome and neither will comparing yourself to others.  It all comes down to you deciding if you are God or not.  Take the time to find a good doctor, mechanic, contractor and church.  You will be off for it.
