But when we find this stuff in the Bible it's ok right?
You might not like some of the things that happened in the bible but it leaves you under no allusions regarding life in a fallen world. If you are trying to say that the bible tells Christians to do bad things then you are way off base.
Nowhere does the bible say I should preach with physical force (unlike the Qur'an), quite the opposite
Matthew 5:38-48 (New International Version)
An Eye for an Eye
38 "You have heard that it was said, 'Eye for eye, and tooth for tooth.' 39 But I tell you, Do not resist an evil person. If someone strikes you on the right cheek, turn to him the other also. 40 And if someone wants to sue you and take your tunic, let him have your cloak as well. 41 If someone forces you to go one mile, go with him two miles. 42 Give to the one who asks you, and do not turn away from the one who wants to borrow from you.Love for Enemies
43 "You have heard that it was said, 'Love your neighbor and hate your enemy.' 44 But I tell you: Love your enemies and pray for those who persecute you, 45 that you may be sons of your Father in heaven. He causes his sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous. 46 If you love those who love you, what reward will you get? Are not even the tax collectors doing that? 47 And if you greet only your brothers, what are you doing more than others? Do not even pagans do that? 48 Be perfect, therefore, as your heavenly Father is perfect.Nowhere does the bible say people should not have a choice to believe or not (unlike the Qur'an), once again the opposite
Revelation 22:11 (New International Version)
11 Let him who does wrong continue to do wrong; let him who is vile continue to be vile; let him who does right continue to do right; and let him who is holy continue to be holy."
All the best,
Stephen
