To all people who are of christian beliefs?

Does it ever bother you, how some (note the word some) people group us into one category and criticize on what that one particular category has gained a notably mixed reputation and what morals that the one partiuclar category has? I know that there are more than 100 branches of christianity, and that they can't identify each one and put a person into it, I just wish if they didn't know to much about what a particular faith's philosphy and beliefs are that they would just plainly not comment on them. This is what really bothers me, when the more "dimwitted" christians are the ones who represent us, and make some of the ones who actually study hard and strive to be the best person they can be, both socially and spiritually, and make it look as if we act in the same manner as they do. Sometimes lifes just not fair.
