I know exactly what you mean
I had a man at work actually harass me about it until i took it further, one day it was so bad that when i left that day i cried all the way home.
It was then that i realised “hang on a minute what am i doing? This is who i am and im not shamed of it”
After that i no longer cared about what anyone else thought because i knew who i was.
I know how this sounds but it was true.
So now my favourite come backs are especially if it’s a male I’m dealing with (I’m female)
“do you feel like a big man picking on a women and her beliefs huh?”
And if I still get a smart comment back, i simply interrupt them and say
“look I’m going to stop you there, I’m done with this conversation you are far too closed minded for this topic so I’m done, we have nothing else to discuss ” and walk off not waiting for their response.
I said this to the man the next day at work and felt so good about might self.
9 times out of 10 you can just hear as your walking off they repeat to themselves “closed minded?” lol
These people don’t understand and don’t really care about understanding I found.
Just hold your head high because we are “vegan or vegetarian or pescatarian and we are proud” lol
