I apologize if you thought I was trying to talk down to religious people. That is never my goal, but religious people tend to take the liberty to aggressively tell me what they believe. I think there is space for my ideological viewpoints as well.
Christians sometimes with certainty of their faith at back of their minds, and desire to see others experience what they believe has changed their lives can be overzealous in their evangelism. They typically mean well. If you antagonize them, however, perhaps because you have had bad experiences in the past, they also may become overbearing and defensive and condemnatory in their interactions with you.
While Christians are expected to take the high road in these sort of situations, they like everyone else are work in progress and may have yet to attain such level of maturity.
If you are generous (in a relationship sense) with Christians, even if friendship is unattainable, you may find yourself able to get along with Christians who themselves also have a generous spirit.
