Nah man if you halve your current meat consumption you are doing a big benefit to society and it’s much easier than going 100%. You don’t really need to go 100% either, if it’s about environment, eating sometimes whatever you want is completely valid, and I don’t think I’ve met any vegan/vegetarian that criticises that.
If you want to sprinkle your beans with a bit of bacon, it’s tasty as hell and not that big of a deal. If you want to eat some lentils with carrots and some slices of chorizo, it’s really fine. Some days you will feel like eating fries with fake fish sticks, some days you will prefer to eat a sandwich with a slice of ham, idc. It’s all really about reducing the intake and then, after doing it, having more freedom for picking higher quality products, which are more expensive but now you can allow them since you eat so much less of them.
