In the past (or even in the present, depending on which country you had the accident to be born in), lusty opponents of religion (not necessarily all religions, of course, often just the one in vogue at the time) were very likely to fail to live out their natural lifespan. These days we just get called trolls. At least we've learned how to keep our heads (in more ways than one). If you air your "Christian views" on a website which is basically of a secular nature, which is your inalienable right, yes you can expect to be subjected to opposing points of view, put fairly directly at times. You call it nasty, I say tomayto. You do not own the default position of humanity.
