Actually, friend, there is a lot of context missing. Books aren't meant to be read one sentence at a time.
I can take a single line from any book and complete alter the meaning of that book by proclaiming that one sentence, alone in a vacuum, is truth.>2:85
Then, you are those [same ones who are] killing one another and evicting a party of your people from their homes, cooperating against them in sin and aggression. And if they come to you as captives, you ransom them, although their eviction was forbidden to you. So do you believe in part of the Scripture and disbelieve in part? Then what is the recompense for those who do that among you except disgrace in worldly life; and on the Day of Resurrection they will be sent back to the severest of punishment. And Allah is not unaware of what you do.>2:190
Fight in the way of Allah those who fight you but do not transgress. Indeed. Allah does not like transgressors.
The phrase you pulled from 2:193 is concerning what to do when someone attacks you. Are Muslims not allowed to defend themselves?>3:21
Those who disbelieve in the signs of Allah and kill the prophets without right and kill those who order justice from among the people - give them tidings of a painful punishment.
Note the "and kill" parts that you conveniently left out.>4:89
That's not what 4:89 says. Nice abridged version there, but look further to 4:90 "Except for those who take refuge with a people between yourselves and whom is a treaty or those who come to you, their hearts strained at [the prospect of] fighting you or fighting their own people. And if Allah had willed, He could have given them power over you, and they would have fought you. So if they remove themselves from you and do not fight you and offer you peace, then Allah has not made for you a cause [for fighting] against them.">5:80
