You are making such a useless point that requires minimal effort or thought. It would be better if you actually shared a tangible concern rather than providing a strawman argument meant to cause an irrational fear in people reading your comment.
For example, you could have shared which group of people you want to be a protected class and is not by Irish law; or which group of people is currently a protected class by Irish law and should not be. At least, then, you would have brought up a real concern about how the Irish government is determining hate speech; because right now, all you are doing is fear mongering.
I think one misunderstanding is the goal behind karma. It’s not to achieve good karma, but to have a net zero karma. A way to reach zero karma is to perform good deeds without announcing or advertising it.
