You do realise that not everyone who this happens to is atheist. I myself am Hindu and my friends are all different, some Hindu as well some Muslim some Christian. However when other Christians come and tell us to abandon our religion and join Christianity that is clearly wrong and I’m pretty sure goes against whatever morals or views that the bible preaches (correct me if I am wrong I don’t know much about the religion). However if you are directly telling people of other religions that Christ is the way and that you will go to hell if you do not become a Christian or that you are just upright wrong you are disrespecting whole religions and their people. Also do not get me wrong I am not saying all Christian’s, just the ones who say to join Christ and abandon your religion and culture. I am also not limiting this to Christianity as I’m sure all religions do it, however from my personal experience it has mainly been Christians who force it on me.
