Mum called me perverse for being gay

Don't do anything drastic. She could come around on the idea with a bit of time.

Am sorry to hear that's horrible there is absolutely nothing wrong with being gay and don't let anyone tell you otherwise

The church is full of gay people unless she is a fundamentalist. Is there anyone you both respect who could mediate?

Your mum is upset and has made a throwaway comment. She'll get used to it

this is slightly left to your deal, but im trans personally. i havent had to deal with religious influences but i know it took about 3 years for my mum to even consider trying to use the correct name
it can be difficult, and if i had to guess id say youre currently living with her
my best advice would be this: dont cut her off, but dont give her free roam either. if you have this conversation again and things get heated, do your best to just say calmly 'i think we both need to calm down before we speak more' and leave the room if possible
having to be the bigger person with your parents really sucks, but if you have kids there will be a day where they may have to do the same to you. recognise that if/when you move out (if you are cohabiting) distance will make things easier, and make it so keeping you as a child is her choice, but you dont have to make the final decision on keeping her as a mother
wish you the best!

i fully understand that youre upset. it sucks when the one person who is meant to love us unconditionally starts adding caveats to letting us access that love
please do yourself a favour and just spend 10 minutes calming down. speak to your girlfriend or watch something on youtube, and just breath. perspective will help you tackle this infinitely more than rage

Remember this is your mum. You should always put her first before any relationships. She is so important and you must make the most of every moment with her. She will realise how important you are to her as well

and it makes peefect sense to want to do that, but this is why im suggesting you just sit down for a few minutes and breath
if you flip, and get angry, and start screaming, and start saying 'i will never talk to you again!!!' you justify what your mother has said to you
but if you react calmly and professionally, remove yourself when annoyed, and stop engaging when she tries to cause arguments, you leave the only person with any improvement to be made as her
its really difficult to do, and screaming into a pillow might help get those initial bursts out. but trust me, in the long run patience really will change so much of the situation

How old are you?
