I met a trendy Christian girl

You gave her what she came for, though she probably doesn't know it.

She thinks she's doing what Jesus wanted from her, ie. spreading the gospel and potentially saving souls from eternal damnation. If one believes in eternal damnation, it would be pretty horrible NOT sppending your time trying to save people from it, like walking past a collapsed bullding and not trying to pull people from the rubble,except much, much worse.

That's what makes it particularly sad that what most (perhaps not all) who publicly witness want is validation of their identity which they get through provoking the criticism and ridicule of outsiders. Later they can tell each other that this criticism and ridicule is evidence of, or even amounts to, persecution, the ultimate sign that your identity is indeed valid.

If one is seriously interested in the teachings of Jesus, they should look long and hard at their reasons for witnessing, to make sure that they are not in fact the sin of pride.

Being truly Christian is very, very hard and balancing the potential damnation of others (about which you can know nothing since judgement is the province of God) against ones own motivations is just one of the difficulties. Being truly Christian is a lot more like agony on the corss than talking to people about stuff they don't want to talk about in coffee shops.
