I agree with you on a vast majority of what you just said especially this:
"I understand that people just got a first impression about something
regarding the bad things, but those things really does not represent what
Christianity is about. If they really want to learn to appreciate
Christianity they should have an eye towards the life of the saints or to the
great achievements that Christianity has achieved in History on behalf of
Humanity."
and this
"As the Holy Father recently said, God is ok with people being atheist if
they really think in their hearts that is the Truth and they try to live life
being better persons in accordance with what they hearlty think it is the
Truth."
I would say you have a good heart. As long as you are good inside which I
believe you are, you have nothing to worry about. But I do appreciate your
love for Christ.
If you ever get a chance sometime and have the technical know-how to do this,
I recommend Hyperbola. It is a very good systemd-free free software distro.
Not to mention stable gnu/linux distro. Encryption is so far hard to
implement on it, but when a gui appears with calamares, I will tell you if
you would like.
It is updated quite frequently by comparison to Trisquel.
If you want to pm me through my contact option you may.
