As an atheist, I WANT Christianity to be a strong religion as truth be told,

As an atheist, your goals for Christianity differ from the goals of Christians and the goals of Christ Himself. As your comment implies, you see Christianity only as a political tool to achieve your political aims. You see it as a way to enforce your desired moral outcomes, not God's moral outcomes. That is not Christianity.

In contrast, a Christian sees his religion as Truth. Christ is the Son of God. He is Lord and King. We obey Christ becomes it is our duty to so. He has tasked us with loving God and loving our neighbours as well as our enemies. Fundamentally, a Christian's main motivation is to achieve God's will, not the will of humans. Therein is the clear distinction between your goals and my goals.

In some cases, I may be able to work you to achieve particular aims. But I will not apologize for calling out your attempt to tell me how I should be acting as a Christian. If I need guidance, I will turn to prayer and the Holy Spirit, not a random atheist on the internet.

You do, of course, have the free will to become accept Christ in your life as King and Saviour and become Christian. It is my hope that you do so.
