Caste(Catholic) Stereotyping

Well I dont know whether I should be posting this or not.But I am doing so because this is something related to my religion and I have been hurt and I want others to understand something.NOTE: This is applicable only to a few people,so those who know they do it please try to avoid it if possible or do it only if it is positive.
Living in a country like India especially in a city like Mumbai where we find so many people belonging to different backgrounds and following different religions this is something I should have expected which I did.But still it hurts when people knowing you reveal certain things about this issue.
Being a catholic I am well aware of the catholic traditions and also the behaviour of catholic people.Well not all catholics but there are a few or i dont know many who spoil the image of catholics and I know that there are catholics not so well accepted by the society because of their habits basically drinking which according to majority people and religions is wrong.Well let me clarify one thing here first catholics are allowed to drink doesnt mean that all catholics drink or all catholics must drink. This point I raise because I have come across the question "Arre you are a catholic na so u drink na" ,"So you eat this and that(non veg stuff) na" "You know how to play the guitar??" "You play football well na" .. Well all these are a few examples which I have come across. Although the last two questions dont hurt but they also are a kind of stereotyping. The first two hurt and hurt real bad especially when I know i dont drink. Let me make it very clear I have no problem with drinking .I have a problem only with excessive drinking. And about eating non veg I dont consider it wrong at all but at the same time I respect the veggies and would avoid eating non veg in front of them.
Also people have a common notion that catholics are party animals .We just party on every occasion and drink at every possible celebration. And this too hurts.And this hurts to the extent that I myself hate those catholics because of which the remaining are stereotyped.
I would like to make it clear that I am not against stereotyping.Well I do it myself .But only if it is a good thought.I dont do it much .But I would like to narrate an example.For me i like gujurati people because i have come across them as the smarter lot of people study wise and also the kind of people who enjoy life balancing it well with their responsibilities.And I say this out of personal experience bcoz I had many gujurati friends in school who were almost all smart.Then I was in a gujurati minority college where i met even more smarter guju ppl.So now whenever I see a gujju I sense that he is a smart person.And if I tell that person that would make that person happy.
Well my aim of writing this is to make the few who have made me feel hurt indirectly that all human beings are not the same.Please dont make an image of a person before you know him based on his looks and most importantly his caste.
Thanks a lot for those people who know what kind of a person I am and not allowing caste to decide My First Impression on them....
