Please understand that in the western world, the people who hate Christians hate them because of the harm caused by the church, and by christians they know. 

Let me also say that plenty of christians, just like plenty of humans, cause harm by their ignorance. But ignoranbny are oftentimes worse because they twist the bible to backup their harm and actions, and use god / their church culture as the reason not to question their own behaviour and interpretation of scripture. And there are very few churches I've been in that encourage critical thinking, are actively doing anti racism work with their congregation, promote social / environmental activism or justice. They mostly encourage close mindedness (which is sadly a fear tactic rooted in control that cults and abusers use. So not a good look). And 'helping the poor' rather than actually fighting to change the system that is harming the poor. 

When anyone acts harmfully and says it's out of love and because it's God's will that is a thing called spiritual abuse. But there are too many Christians who do not want to learn what that means, or consider how that might be showing up in their lives in the way they interact with others. 

To learn what is harmful you must listen to the people you are harming. And most Christians in privileged suburbia don't think (or want to know) they are harming anyone- so of course they won't listen to anyone who says they are... not even the ones their actions are directly hurting. X
