Catholics aren't generally young-Earth creationists, and overall the Church argues the age of the earth is a scientific not a religious question.
I totally agree there are many religious schools which are extremely high quality. Despite a few strange views at the school I went to, the general quality of education was quite high. However, I refuse to ignore the many other examples of schools which are not high quality. They should be called out, and there's no way I want my tax dollars going to teach their nonsense.
The thing is - the average school is terrible. NAEP scores show less than 25% reach "basic" proficiency in math, and reading is even worse.
I can't find any comparable stats on just religious schools, but I strongly suspect they are, on average, performing substantially better than non-religious schools. The reasons for that are more to do with the students than the schools, but the exact reason is inconsequential - the point is that people are targeting them because of the religious aspect and not the quality of education.
The typical claim of evolution is illogical. Even if a religious school solely and exclusively taught creationism while not even paying lip service to the controversy (which few to none do), it's not at all like a child's education would be permanently crippled. As the most important things learned in basic education are not facts, but skills - reading, writing, and arithmetic in particular.
