It seems to me it would be more democratic. Democracy means the majority rules. We've put limits on that so that no one's individual rights would be trampled, and rightly so. But if it is possible to cater to many groups with a public service, without diminishing the efficacy of that service, that seems to me to be more democratic than a take-it-or-leave-it approach to that service. The real question, then, is: should education be representative of the population being educated? If education is to be democratic, then I would argue that it should be representative.

BTW, a UN tribunal agrees with me in one respect. One of Canada's Protestant groups took the province of Ontario to court over discrimination, and the decision was that our funding model (Catholic and Public schools, but no funding for anybody else) was discriminatory. We should be funding either everybody or nobody. The judges didn't force the province to recitfy the situation, though several other provinces took it upon themselves to eliminate the Catholic system as a result.
