We've all heard of racism, sexism, ageism, speciesism (speciesism is illogical), etc.
I've been trying to come up for a label for those who discriminate based on a person's stage of development (those still not born after conception). The best I came up with until today was developmentism. It just doesn't work.
Then, today, it came to me: stageism (not stagism; hard "g").
What do you think? Do you have any better ideas? (I think it should be one word, preferably three syllables.)
