Just keep the peace until you’re able to move on and broaden your horizon with new people. Religious people tend to be the same as political people. No matter how thought out your response, no matter what facts you have on your side, you aren’t going to change other people’s minds.

However, the way I discovered to keep friends and believe what I want is to just avoid the topic all together. I know you have a class specifically about religion, but just keep your head down until it’s over. June isn’t that far away. You’re in a rather difficult place because you’re in a catholic school. Which means thinking the way you do is not only against the social norms, it’s against the majority of the population at your school.

Hang in there. Don’t give up. Just do what you have to do to get by. And if you’re ever forced to memorize a verse of your choice, always go with: John 11:35 ? I’ll let you look it up and see why.

Eventually you will learn what fight to pick and what to just tag along....... Live and let die

You're the only person who knows the answer to that question.
Is it worth it to you?

Don't waste your energy. It won't matter. Finish your time and move on. Find some friends with open minds and see the world.

Catherine, finish up yer education, get to uni and start a new life. You'll make new friends and a new life. Be brave x

The uniform is the only thing they got right. ?

That can't be easy. I have found that asking questions, especially why questions can lead down more constructive paths than arguing. If they see you as questioning rather than opposition, conversation can often be far more civil. Especially if you have leading questions.

Also, one thing I've found to be very helpful in these kinds of conversations is considering their view. For a really well explained explanation, I suggest this video:

You're so close. It sucks now, but you have a couple months left and then you don't have to worry about it ever again.

Introduce logic and reason to conversations that don't involve religion and let your friends learn through experience. Choose topics that create the least conflict, when you get the chance, RUN.

Smile sweetly, diploma in hand and move on ?

I would only bother continuing with the conversation if I saw some form of thought or reasoning from the other party. If you're only getting a strong negative push back, these may not be the type of people to try and have a reasonable debate with.
Just my two cents.

keep plugging away. as they get older some of what you say now may resonate

you need to graduate. don’t make waves.

I feel your pain.

Forgive the biblical allusion but you're in the lion's den. It could be worse though. RCs accept old Earth origins and descent of man through evolution. Two things that hold them back are transubstantiation and exorcism. If you don't consider these acceptable foibles then you have to question your being there in the first place. But if you can focus on the common ground you share with your RC peers I think they'll remember you in a better light after you graduate. Then, if you are intent, would be a better time to prosthelytize.

In a few months you'll be in college; it's a lot easier to have the discussions you desire there.

I wonder if you could start discussions (as you say), but do them in such a way that you are more initiating and moderating, so as to let your friends/classmates argue the sides. This could get the critical thoughts going without you having to be in the line of fire.

Hang in there. You will free of the dogma soon.

I rarely pushed the issue in that identical situation and came through it a stronger person having witnessed the delusion of Belief...hang in there.

Religion has spoken to a hushed audititorium for eons with a mic, even now they hold sway in society.
As a non believer you also have a right to exist and not believe.

I suggest you try a different tack with your classmates.
Try SE

Best to continue asking them questions about what they based their beliefs on, who.knows if there might be a few closet free thinkers there?

Makes sense that you would be receiving this kind of unwanted attention from those at your school since they're in a...well, religious school! Did your parents place you in there or something? Are your "friends" in the school with you? If so, that would make sense too...I don't know many "non-believers" who attend specific "believer" schools. I wouldn't waste my time trying to discuss things with people who clearly think differently than you do. Just do your time and get out when your parole date arrives.

You're in high school?

No. It's like trying to convince a cow they could walk right through that string fence.
Stick out the next few weeks and walk away smiling.

Stay strong, bide your time, and say "adios, motherfuckers!"
