personally i agree that what the woman did wasn't very loving in the way you describe. indeed the only people jesus judged were the religious, the people who thought they were better than everyone else, judging other people. from that perspective then what she did wasn't very christian. indeed jesus hung round with prostitutes, the tax collectors (contextually bad people), and such, treating them as human beings because he loved them. to do otherwise would not be chrit-like, it would not be christian.
personally i am a christian myself, but in no way see myself as religious. a religion is a set of beliefs, a ritualistic system, which must be followed rigidly. christianity is based on jesus, who says throughout the gospels that the whole law is summed up into "do unto others as you would have them do to you". he also says he came not to abolish the law but to fulfill it. this is to say that jesus came not so that we would be religious and judge other people, but so that we could have a relationship with god, with jesus. jesus never said follow my philosophy, follow my religion, he said follow me. jesus came to give us "life in abundance", not be miserable religious people doing things because we fear god will strike us down.
in fairness i do not wish to judge the woman you came across. as with anyone she has many insecurities, and perhaps her faith is what gives her security. her expression of this appears very negative however. i'd just like to point out that to judge a faith by one person is not a very logical thing to do in itself. we are all human and make mistakes, and as such none of us are perfect. only jesus is, and from only him can you understand what faith truly means.
i wont be on this site very much so if you have any questions please email me at [email protected]. if you want to challenge anything i've said then by all means do. if what you seek is the truth, than your mind should be open. the problem is many have already closed theirs. even better would be to ask a church leader, someone who knows what they're talking about, who isn't religious but who knows what it is to be a christian. of course not all church leaders are great, otherwise every church would be a great success, but there are many good people around if you look. even better than that though would be to read the bible itself. the gospels are a great place to start because it's all about jesus and being the foundation of the faith he's certainly important.
i apologise if it seems like i've been preaching, that wasn't my intention, but i'm still learning too.
