> But other people very much do not want this option taken away from them and step one to talking about this is at least admitting that, yes, algebra is being replaced.

Of course algebra is being replaced, where do I say anything different.

I guess my mistake is assuming my interlocutors are not idiots and want to debate the reason of the replacement rather than just staying on "I like Algebra so I'm crying like a baby".

> And people have a problem with what is being replaced.

This is what I don't understand. They don't have any arguments to support the fact that the replacement is not bringing more supported "pro" than "con".

All they say is "I can see one good thing to Algebra, so it implies that this measure can only be a bad one", which is obviously incorrect. In real life, measures usually replace things that are not all bad by things that are better. The point is that you need to weight the pros and the cons. Here, it feels like people are just saying "I don't want to hear the pros, I know one con, and it means it's a bad idea".

I personally like Algebra, and I would have loved it to stay. The same way I like the convenience of some fastfood. But when a study shows that for the same price, they can replace a fastfood menu to a better menu in a school, the normal thing to do is to weight the pros and cons, not just cry because I prefer fastfood.

It is interesting to see that some people who present themselves as on the side of reason will act so irrationally to oppose some proposal without caring of the pros and cons, just because it feels negative in their feelings.
