If Muggles are unaware of Wizards, why do they agree to send their kids to Wizarding schools?

My wife, a shrewd Bulgarian (and a supporter of the Vratsa Vultures Quidditch Team), looked up from reading GoF and posed the following questions:

If muggles are protected from knowledge of the wizarding world, why do muggle parents (like those of Hermione Granger and Lily Evans Potter) appear to accept so easily the existence of magic? And, more incredibly, why do they agree to the education of their children in wizarding schools where the children are prepared to live in clandestine wizard communities rather than participate in the wider muggle world? I quote Aunt Petunia in PS/SS:

"...for my mother and father,oh no, it was Lily this and Lily that, they were proud of having a witch in the family."
