I am not against Christianity, I am against Evangelical fascism (very much wahabbism) which isn't Christianity.
Actually 'evangelism' (minus the fascist part) - spreading the 'Word' - is an important part of Christianity (just behind love for others):
Matthew 28:18-20
And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth.
Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world. Amen.
We do this because we love the lost -- who we once were -- but its understood that we are just to bring the 'Word', not bludgeon people with it:
Luke 9:2-6
And he sent them to preach the kingdom of God, and to heal the sick.
And he said unto them, Take nothing for your journey, neither staves, nor scrip, neither bread, neither money; neither have two coats apiece.
And whatsoever house ye enter into, there abide, and thence depart.
And whosoever will not receive you, when ye go out of that city, shake off the very dust from your feet for a testimony against them.
And they departed, and went through the towns, preaching the gospel, and healing every where.
Now I'm not going to deny that history is laced with examples of 'convert or die' "programs", but these actions were/are clearly unBiblical (i.e., 'sin'). Unlike another "religion", there is no basis in Christianity where forced conversion is allowed - or even deemed possible. We get the privilege to bring the Word, but only God can save:
Ezekiel 36:24-28
For I will take you from among the heathen, and gather you out of all countries, and will bring you into your own land.
Then will I sprinkle clean water upon you, and ye shall be clean: from all your filthiness, and from all your idols, will I cleanse you.
A new heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh.
And I will put my spirit within you, and cause you to walk in my statutes, and ye shall keep my judgments, and do them.
And ye shall dwell in the land that I gave to your fathers; and ye shall be my people, and I will be your God.
Only God can change our hearts of stone, and put HIS Spirit within us to make us clean. And the only way this can come is through belief in Jesus Christ as God's only Begotten Son and Saviour of us sinners. Only through Him can we be Just before God.
There is a big disparity between the tenets of Christianity and that which the belivers actually practice.
And in anycase we got the Word form God millenia before the birth of Christ from a different Messiah. We dont need the words of a mortal Missionary who got it all wrong.
